# Google Secure LDAP **(CORE ONLY)**
> [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/46391) in GitLab 11.9.
[Google Cloud Identity](https://cloud.google.com/identity/) provides a Secure
LDAP service that can be configured with GitLab for authentication and group sync.
Secure LDAP requires a slightly different configuration than standard LDAP servers.
The steps below cover:
- Configuring the Secure LDAP Client in the Google Admin console.
- Required GitLab configuration.
## Configuring Google LDAP client
1. Navigate to <https://admin.google.com/Dashboard> and sign in as a GSuite domain administrator.
1. Go to **Apps > LDAP > Add Client**.
1. Provide an `LDAP client name` and an optional `Description`. Any descriptive
values are acceptable. For example, the name could be 'GitLab' and the
description could be 'GitLab LDAP Client'. Click the **Continue** button.
![Add LDAP Client Step 1](img/google_secure_ldap_add_step_1.png)
1. Set **Access Permission** according to your needs. You must choose either
'Entire domain (GitLab)' or 'Selected organizational units' for both 'Verify user
credentials' and 'Read user information'. Select 'Add LDAP Client'
TIP: **Tip:** If you plan to use GitLab [LDAP Group Sync](ldap-ee.md#group-sync)
, turn on 'Read group information'.
![Add LDAP Client Step 2](img/google_secure_ldap_add_step_2.png)
1. Download the generated certificate. This is required for GitLab to
communicate with the Google Secure LDAP service. Save the downloaded certificates
for later use. After downloading, click the **Continue to Client Details** button.
1. Expand the **Service Status** section and turn the LDAP client 'ON for everyone'.
After selecting 'Save', click on the 'Service Status' bar again to collapse
and return to the rest of the settings.
1. Expand the **Authentication** section and choose 'Generate New Credentials'.
Copy/note these credentials for later use. After selecting 'Close', click
on the 'Authentication' bar again to collapse and return to the rest of the settings.
Now the Google Secure LDAP Client configuration is finished. The screenshot below
shows an example of the final settings. Continue on to configure GitLab.
![LDAP Client Settings](img/google_secure_ldap_client_settings.png)
## Configuring GitLab
Edit GitLab configuration, inserting the access credentials and certificate
obtained earlier.
The following are the configuration keys that need to be modified using the
values obtained during the LDAP client configuration earlier:
- `bind_dn`: The access credentials username
- `password`: The access credentials password
- `cert`: The `.crt` file text from the downloaded certificate bundle
- `key`: The `.key` file text from the downloaded certificate bundle
**For Omnibus installations**
1. Edit `/etc/gitlab/gitlab.rb`:
```ruby
gitlab_rails['ldap_enabled'] = true
gitlab_rails['ldap_servers'] = YAML.load <<-EOS # remember to close this block with 'EOS' below
main: # 'main' is the GitLab 'provider ID' of this LDAP server
label: 'Google Secure LDAP'
host: 'ldap.google.com'
port: 636
uid: 'uid'
bind_dn: 'DizzyHorse'
password: 'd6V5H8nhMUW9AuDP25abXeLd'
encryption: 'simple_tls'
verify_certificates: true

<!-- ## Troubleshooting
Include any troubleshooting steps that you can foresee. If you know beforehand what issues
one might have when setting this up, or when something is changed, or on upgrading, it's
important to describe those, too. Think of things that may go wrong and include them here.
This is important to minimize requests for support, and to avoid doc comments with
questions that you know someone might ask.
Each scenario can be a third-level heading, e.g. `### Getting error message X`.
If you have none to add when creating a doc, leave this section in place
but commented out to help encourage others to add to it in the future. -->

# How to configure LDAP with GitLab CE
Managing a large number of users in GitLab can become a burden for system administrators. As an organization grows so do user accounts. Keeping these user accounts in sync across multiple enterprise applications often becomes a time consuming task.
In this guide we will focus on configuring GitLab with Active Directory. [Active Directory](https://en.wikipedia.org/wiki/Active_Directory) is a popular LDAP compatible directory service provided by Microsoft, included in all modern Windows Server operating systems.
GitLab has supported LDAP integration since [version 2.2](https://about.gitlab.com/releases/2012/02/22/gitlab-version-2-2/). With GitLab LDAP [group syncing](../how_to_configure_ldap_gitlab_ee/index.md#group-sync) being added to GitLab Enterprise Edition in [version 6.0](https://about.gitlab.com/releases/2013/08/20/gitlab-6-dot-0-released/). LDAP integration has become one of the most popular features in GitLab.
## Getting started
### Choosing an LDAP Server
The main reason organizations choose to utilize a LDAP server is to keep the entire organization's user base consolidated into a central repository. Users can access multiple applications and systems across the IT environment using a single login. Because LDAP is an open, vendor-neutral, industry standard application protocol, the number of applications using LDAP authentication continues to increase.
There are many commercial and open source [directory servers](https://en.wikipedia.org/wiki/Directory_service#LDAP_implementations) that support the LDAP protocol. Deciding on the right directory server highly depends on the existing IT environment in which the server will be integrated with.
For example, [Active Directory](https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2012-R2-and-2012/hh831484(v=ws.11)) is generally favored in a primarily Windows environment, as this allows quick integration with existing services. Other popular directory services include:
- [Oracle Internet Directory](https://www.oracle.com/middleware/technologies/internet-directory.html)
- [OpenLDAP](https://www.openldap.org/)
- [389 Directory](http://directory.fedoraproject.org/)
- [OpenDJ (Renamed to Forgerock Directory Services)](https://www.forgerock.com/platform/directory-services)
- [ApacheDS](https://directory.apache.org/)
> GitLab uses the [Net::LDAP](https://rubygems.org/gems/net-ldap) library under the hood. This means it supports all [IETF](https://tools.ietf.org/html/rfc2251) compliant LDAPv3 servers.
### Active Directory (AD)
We won't cover the installation and configuration of Windows Server or Active Directory Domain Services in this tutorial. There are a number of resources online to guide you through this process:
- Install Windows Server 2012 - (`technet.microsoft.com`) - [Installing Windows Server 2012](https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2012-R2-and-2012/jj134246(v=ws.11))
- Install Active Directory Domain Services (AD DS) (`technet.microsoft.com`) - [Install Active Directory Domain Services](https://docs.microsoft.com/en-us/windows-server/identity/ad-ds/deploy/install-active-directory-domain-services--level-100-#BKMK_PS)
> **Shortcut:** You can quickly install AD DS via PowerShell using
`Install-WindowsFeature AD-Domain-Services -IncludeManagementTools`
### Creating an AD **OU** structure
Configuring organizational units (**OU**s) is an important part of setting up Active Directory. **OU**s form the base for an entire organizational structure. Using GitLab as an example we have designed the **OU** structure below using the geographic **OU** model. In the Geographic Model we separate **OU**s for different geographic regions.
| GitLab **OU** Design | GitLab AD Structure |
| :----------------------------: | :------------------------------: |
| ![GitLab OU Design](img/gitlab_ou.png) | ![GitLab AD Structure](img/ldap_ou.gif) |
Using PowerShell you can output the **OU** structure as a table (_all names are examples only_):
```ps
Get-ADObject -LDAPFilter "(objectClass=*)" -SearchBase 'OU=GitLab INT,DC=GitLab,DC=org' -Properties CanonicalName | Format-Table Name,CanonicalName -A
```
```plaintext
OU CanonicalName

## GitLab LDAP configuration
The initial configuration of LDAP in GitLab requires changes to the `gitlab.rb` configuration file (`/etc/gitlab/gitlab.rb`). Below is an example of a complete configuration using an Active Directory.
The two Active Directory specific values are `active_directory: true` and `uid: 'sAMAccountName'`. `sAMAccountName` is an attribute returned by Active Directory used for GitLab usernames. See the example output from `ldapsearch` for a full list of attributes a "person" object (user) has in **AD** - [`ldapsearch` example](#using-ldapsearch-unix)
> Both group_base and admin_group configuration options are only available in GitLab Enterprise Edition. See [GitLab EE - LDAP Features](../how_to_configure_ldap_gitlab_ee/index.md#gitlab-enterprise-edition---ldap-features) **(STARTER ONLY)**
### Example `gitlab.rb` LDAP
```ruby
gitlab_rails['ldap_enabled'] = true
gitlab_rails['ldap_servers'] = {
'main' => {
'label' => 'GitLab AD',

## Security improvements (LDAPS)
Security is an important aspect when deploying an LDAP server. By default, LDAP traffic is transmitted unsecured. LDAP can be secured using SSL/TLS called LDAPS, or commonly "LDAP over SSL".
Securing LDAP (enabling LDAPS) on Windows Server 2012 involves installing a valid SSL certificate. For full details see Microsoft's guide [How to enable LDAP over SSL with a third-party certification authority](https://support.microsoft.com/en-us/help/321051/how-to-enable-ldap-over-ssl-with-a-third-party-certification-authority)
> By default a LDAP service listens for connections on TCP and UDP port 389. LDAPS (LDAP over SSL) listens on port 636
### Testing your AD server
#### Using **AdFind** (Windows)
You can use the [`AdFind`](https://social.technet.microsoft.com/wiki/contents/articles/7535.adfind-command-examples.aspx) utility (on Windows based systems) to test that your LDAP server is accessible and authentication is working correctly. This is a freeware utility built by [Joe Richards](http://www.joeware.net/freetools/tools/adfind/index.htm).
**Return all objects**
You can use the filter `objectclass=*` to return all directory objects.
```shell
adfind -h ad.example.org:636 -ssl -u "CN=GitLabSRV,CN=Users,DC=GitLab,DC=org" -up Password1 -b "OU=GitLab INT,DC=GitLab,DC=org" -f (objectClass=*)
```
**Return single object using filter**
You can also retrieve a single object by **specifying** the object name or full **DN**. In this example we specify the object name only `CN=Leroy Fox`.
```shell
adfind -h ad.example.org:636 -ssl -u "CN=GitLabSRV,CN=Users,DC=GitLab,DC=org" -up Password1 -b "OU=GitLab INT,DC=GitLab,DC=org" -f (&(objectcategory=person)(CN=Leroy Fox))”
```
#### Using **ldapsearch** (Unix)
You can use the `ldapsearch` utility (on Unix based systems) to test that your LDAP server is accessible and authentication is working correctly. This utility is included in the [`ldap-utils`](https://wiki.debian.org/LDAP/LDAPUtils) package.
**Return all objects**
You can use the filter `objectclass=*` to return all directory objects.
```shell
ldapsearch -D "CN=GitLabSRV,CN=Users,DC=GitLab,DC=org" \
-w Password1 -p 636 -h ad.example.org \
-b "OU=GitLab INT,DC=GitLab,DC=org" -Z \
-s sub "(objectclass=*)"
```
**Return single object using filter**
You can also retrieve a single object by **specifying** the object name or full **DN**. In this example we specify the object name only `CN=Leroy Fox`.
```shell
ldapsearch -D "CN=GitLabSRV,CN=Users,DC=GitLab,DC=org" -w Password1 -p 389 -h ad.example.org -b "OU=GitLab INT,DC=GitLab,DC=org" -Z -s sub "CN=Leroy Fox"
```
**Full output of `ldapsearch` command:** - Filtering for _CN=Leroy Fox_

## Basic user authentication
After configuring LDAP, basic authentication will be available. Users can then login using their directory credentials. An extra tab is added to the GitLab login screen for the configured LDAP server (e.g "**GitLab AD**").
![GitLab OU Structure](img/user_auth.gif)
Users that are removed from the LDAP base group (e.g `OU=GitLab INT,DC=GitLab,DC=org`) will be **blocked** in GitLab. [More information](../ldap.md#security) on LDAP security.
If `allow_username_or_email_login` is enabled in the LDAP configuration, GitLab will ignore everything after the first '@' in the LDAP username used on login. Example: The username `jon.doe@example.com` is converted to `jon.doe` when authenticating with the LDAP server. Disable this setting if you use `userPrincipalName` as the `uid`.
## LDAP extended features on GitLab EE
With [GitLab Enterprise Edition (EE)](https://about.gitlab.com/pricing/), besides everything we just described, you'll
have extended functionalities with LDAP, such as:
- Group sync
- Group permissions
- Updating user permissions
- Multiple LDAP servers
Read through the article on [LDAP for GitLab EE](../how_to_configure_ldap_gitlab_ee/index.md) **(STARTER ONLY)** for an overview.
<!-- ## Troubleshooting
Include any troubleshooting steps that you can foresee. If you know beforehand what issues
one might have when setting this up, or when something is changed, or on upgrading, it's
important to describe those, too. Think of things that may go wrong and include them here.
This is important to minimize requests for support, and to avoid doc comments with
questions that you know someone might ask.
Each scenario can be a third-level heading, e.g. `### Getting error message X`.
If you have none to add when creating a doc, leave this section in place
but commented out to help encourage others to add to it in the future. -->

# How to configure LDAP with GitLab EE **(STARTER ONLY)**
This article expands on [How to Configure LDAP with GitLab CE](../how_to_configure_ldap_gitlab_ce/index.md). Make sure to read through it before moving forward.
## GitLab Enterprise Edition - LDAP features
[GitLab Enterprise Edition (EE)](https://about.gitlab.com/pricing/) has several advantages when it comes to integrating with Active Directory (LDAP):
- [Administrator Sync](../ldap-ee.md#administrator-sync): As an extension of group sync, you can automatically manage your global GitLab administrators. Specify a group CN for `admin_group` and all members of the LDAP group will be given administrator privileges.
- [Group Sync](#group-sync): This allows GitLab group membership to be automatically updated based on LDAP group members.
- [Multiple LDAP servers](#multiple-ldap-servers): The ability to configure multiple LDAP servers. This is useful if an organization has different LDAP servers within departments. This is not designed for failover. We're working on [supporting LDAP failover](https://gitlab.com/gitlab-org/gitlab/-/issues/139) in GitLab.
- Daily user synchronization: Once a day, GitLab will run a synchronization to check and update GitLab users against LDAP. This process updates all user details automatically.
In the following section, you'll find a description of each of these features. Read through [LDAP GitLab EE docs](../ldap-ee.md) for complementary information.
![GitLab OU Structure](img/admin_group.png)
All members of the group `Global Admins` will be given **administrator** access to GitLab, allowing them to view the `/admin` dashboard.
### Group Sync
Group syncing allows AD (LDAP) groups to be mapped to GitLab groups. This provides more control over per-group user management. To configure group syncing edit the `group_base` **DN** (`'OU=Global Groups,OU=GitLab INT,DC=GitLab,DC=org'`). This **OU** contains all groups that will be associated with [GitLab groups](../../../user/group/index.md).
#### Creating group links - example
As an example, let's suppose we have a "UKGov" GitLab group, which deals with confidential government information. Therefore, users of this group must be given the correct permissions to projects contained within the group. Granular group permissions can be applied based on the AD group.
**UK Developers** of our "UKGov" group are given **"developer"** permissions.
_The developer permission allows the development staff to effectively manage all project code, issues, and merge requests._
**UK Support** staff of our "UKGov" group are given **"reporter"** permissions.
_The reporter permission allows support staff to manage issues, labels, and review project code._
**US People Ops** of our "UKGov" group are given **"guest"** permissions.
![Creating group links](img/group_linking.gif)
> Guest permissions allows people ops staff to review and lodge new issues while allowing no read or write access to project code or [confidential issues](../../../user/project/issues/confidential_issues.md#permissions-and-access-to-confidential-issues) created by other users.
See the [permission list](../../../user/permissions.md) for complementary information.
#### Group permissions - example
Considering the previous example, our staff will have
access to our GitLab instance with the following structure:
![GitLab OU Structure](img/group_link_final.png)
Using this permission structure in our example allows only UK staff access to sensitive information stored in the projects code, while still allowing other teams to work effectively. As all permissions are controlled via AD groups new users can be quickly added to existing groups. New group members will then automatically inherit the required permissions.
> [More information](../ldap-ee.md#group-sync) on group syncing.
### Updating user permissions - new feature
Since GitLab [v8.15](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/822) LDAP user permissions can now be manually overridden by an admin user. To override a user's permissions visit the groups **Members** page and select **Edit permissions**.
![Setting manual permissions](img/manual_permissions.gif)
### Multiple LDAP servers
GitLab EE can support multiple LDAP servers. Simply configure another server in the `gitlab.rb` file within the `ldap_servers` block. In the example below we configure a new secondary server with the label **GitLab Secondary AD**. This is shown on the GitLab login screen. Large enterprises often utilize multiple LDAP servers for segregating organizational departments.
![Multiple LDAP Servers Login](img/multi_login.gif)
Considering the example illustrated on the image above,
our `gitlab.rb` configuration would look like:
```ruby
gitlab_rails['ldap_enabled'] = true
gitlab_rails['ldap_servers'] = {
'main' => {
'label' => 'GitLab AD',
'host' => 'ad.example.org',
'port' => 636,
'uid' => 'sAMAccountName',
'method' => 'ssl',
'bind_dn' => 'CN=GitLabSRV,CN=Users,DC=GitLab,DC=org',
'password' => 'Password1',
'active_directory' => true,
'base' => 'OU=GitLab INT,DC=GitLab,DC=org',
'group_base' => 'OU=Global Groups,OU=GitLab INT,DC=GitLab,DC=org',
'admin_group' => 'Global Admins'
},
'secondary' => {
'label' => 'GitLab Secondary AD',
'host' => 'ad-secondary.example.net',
'port' => 636,
'uid' => 'sAMAccountName',
'method' => 'ssl',
'bind_dn' => 'CN=GitLabSRV,CN=Users,DC=GitLab,DC=com',
'password' => 'Password1',
'active_directory' => true,
'base' => 'OU=GitLab Secondary,DC=GitLab,DC=com',
'group_base' => 'OU=Global Groups,OU=GitLab INT,DC=GitLab,DC=com',
'admin_group' => 'Global Admins'
}
}
```
## Conclusion
Integration of GitLab with Active Directory (LDAP) reduces the complexity of user management.
It has the advantage of improving user permission controls, while easing the deployment of GitLab into an existing [IT environment](https://www.techopedia.com/definition/29199/it-infrastructure). GitLab EE offers advanced group management and multiple LDAP servers.
With the assistance of the [GitLab Support](https://about.gitlab.com/support/) team, setting up GitLab with an existing AD/LDAP solution will be a smooth and painless process.
<!-- ## Troubleshooting

# LDAP Additions in GitLab EE **(STARTER ONLY)**
This section documents LDAP features specific to GitLab Enterprise Edition
[Starter](https://about.gitlab.com/pricing/#self-managed) and above.
For documentation relevant to both Community Edition and Enterprise Edition,
see the main [LDAP documentation](ldap.md).
NOTE: **Note:**
[Microsoft Active Directory Trusts](https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2008-R2-and-2008/cc771568(v=ws.10)) are not supported
## Use cases
- User sync: Once a day, GitLab will update users against LDAP.
- Group sync: Once an hour, GitLab will update group membership
based on LDAP group members.
## Multiple LDAP servers
With GitLab Enterprise Edition Starter, you can configure multiple LDAP servers
that your GitLab instance will connect to.
To add another LDAP server:
1. Duplicating the settings under [the main configuration](ldap.md#configuration).
1. Edit them to match the additional LDAP server.
Be sure to choose a different provider ID made of letters a-z and numbers 0-9.
This ID will be stored in the database so that GitLab can remember which LDAP
server a user belongs to.
## User sync
Once per day, GitLab will run a worker to check and update GitLab
users against LDAP.
The process will execute the following access checks:
- Ensure the user is still present in LDAP.
- If the LDAP server is Active Directory, ensure the user is active (not
blocked/disabled state). This will only be checked if
`active_directory: true` is set in the LDAP configuration.
NOTE: **Note:**
In Active Directory, a user is marked as disabled/blocked if the user
account control attribute (`userAccountControl:1.2.840.113556.1.4.803`)
has bit 2 set. See <https://ctovswild.com/2009/09/03/bitmask-searches-in-ldap/>
for more information.
The user will be set to `ldap_blocked` state in GitLab if the above conditions
fail. This means the user will not be able to login or push/pull code.
The process will also update the following user information:
- Email address.
- If `sync_ssh_keys` is set, SSH public keys.
- If Kerberos is enabled, Kerberos identity.
NOTE: **Note:**
The LDAP sync process updates existing users while new users will
be created on first sign in.
## Group Sync
If your LDAP supports the `memberof` property, when the user signs in for the
first time GitLab will trigger a sync for groups the user should be a member of.
That way they don't need to wait for the hourly sync to be granted
access to their groups and projects.
A group sync process will run every hour on the hour, and `group_base` must be set
in LDAP configuration for LDAP synchronizations based on group CN to work. This allows
GitLab group membership to be automatically updated based on LDAP group members.
The `group_base` configuration should be a base LDAP 'container', such as an
'organization' or 'organizational unit', that contains LDAP groups that should
be available to GitLab. For example, `group_base` could be
`ou=groups,dc=example,dc=com`. In the config file it will look like the
following.
**Omnibus configuration**
1. Edit `/etc/gitlab/gitlab.rb`:
```ruby
gitlab_rails['ldap_servers'] = YAML.load <<-EOS
main:
## snip...
##
## Base where we can search for groups
##
## Ex. ou=groups,dc=gitlab,dc=example
##
##
group_base: ou=groups,dc=example,dc=com
EOS
```
1. [Apply your changes to GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure).
**Source configuration**
1. Edit `/home/git/gitlab/config/gitlab.yml`:
```yaml
production:
ldap:
servers:
main:
# snip...
group_base: ou=groups,dc=example,dc=com
```
1. [Restart GitLab](../restart_gitlab.md#installations-from-source) for the changes to take effect.
To take advantage of group sync, group owners or maintainers will need to [create one
or more LDAP group links](#adding-group-links).
NOTE: **Note:**
If an LDAP user is a group member when LDAP Synchronization is added, and they are not part of the LDAP group, they will be removed from the group.
### Adding group links
Once [group sync has been configured](#group-sync) on the instance, one or more LDAP
groups can be linked to a GitLab group to grant their members access to its
contents.
Group owners or maintainers can add and use LDAP group links by:
1. Navigating to the group's **Settings > LDAP Synchronization** page. Here, one or more
LDAP groups and [filters](#filters-premium-only) can be linked to this GitLab group,
each one with a configured [permission level](../../user/permissions.md#group-members-permissions)
for its members.
1. Updating the group's membership by navigating to the group's **Settings > Members**
page and clicking **Sync now**.
### Filters **(PREMIUM ONLY)**
In GitLab Premium, you can add an LDAP user filter for group synchronization.
Filters allow for complex logic without creating a special LDAP group.
To sync GitLab group membership based on an LDAP filter:
1. Open the **LDAP Synchronization** page for the GitLab group.
1. Select **LDAP user filter** as the **Sync method**.
1. Enter an LDAP user filter in the **LDAP user filter** field.
The filter must comply with the
syntax defined in [RFC 2254](https://tools.ietf.org/search/rfc2254).
## Administrator sync
As an extension of group sync, you can automatically manage your global GitLab
administrators. Specify a group CN for `admin_group` and all members of the
LDAP group will be given administrator privileges. The configuration will look
like the following.
NOTE: **Note:**
Administrators will not be synced unless `group_base` is also
specified alongside `admin_group`. Also, only specify the CN of the admin
group, as opposed to the full DN.
**Omnibus configuration**
1. Edit `/etc/gitlab/gitlab.rb`:
```ruby
gitlab_rails['ldap_servers'] = YAML.load <<-EOS
main:
## snip...
##
## Base where we can search for groups
##
## Ex. ou=groups,dc=gitlab,dc=example
##
##
group_base: ou=groups,dc=example,dc=com
##
## The CN of a group containing GitLab administrators
##
## Ex. administrators
##
## Note: Not `cn=administrators` or the full DN
##
##
admin_group: my_admin_group
EOS
```
1. [Apply your changes to GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure).
**Source configuration**
1. Edit `/home/git/gitlab/config/gitlab.yml`:
```yaml
production:
ldap:
servers:
main:
# snip...
group_base: ou=groups,dc=example,dc=com
admin_group: my_admin_group
```
1. [Restart GitLab](../restart_gitlab.md#installations-from-source) for the changes to take effect.
## Global group memberships lock
"Lock memberships to LDAP synchronization" setting allows instance administrators
to lock down user abilities to invite new members to a group.
When enabled, the following applies:
- Only administrator can manage memberships of any group including access levels.
- Users are not allowed to share project with other groups or invite members to
a project created in a group.
## Adjusting LDAP user sync schedule
> Introduced in GitLab Enterprise Edition Starter.
NOTE: **Note:**
These are cron formatted values. You can use a crontab generator to create
these values, for example <http://www.crontabgenerator.com/>.
By default, GitLab will run a worker once per day at 01:30 a.m. server time to
check and update GitLab users against LDAP.
You can manually configure LDAP user sync times by setting the
following configuration values. The example below shows how to set LDAP user
sync to run once every 12 hours at the top of the hour.
**Omnibus installations**
1. Edit `/etc/gitlab/gitlab.rb`:
```ruby
gitlab_rails['ldap_sync_worker_cron'] = "0 */12 * * *"
```
1. [Reconfigure GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure) for the changes to take effect.
**Source installations**
1. Edit `config/gitlab.yaml`:
```yaml
cron_jobs:
ldap_sync_worker_cron:
"0 */12 * * *"
```
1. [Restart GitLab](../restart_gitlab.md#installations-from-source) for the changes to take effect.
## Adjusting LDAP group sync schedule
NOTE: **Note:**
These are cron formatted values. You can use a crontab generator to create
these values, for example <http://www.crontabgenerator.com/>.
By default, GitLab will run a group sync process every hour, on the hour.
CAUTION: **Important:**
It's recommended that you do not run too short intervals as this
could lead to multiple syncs running concurrently. This is primarily a concern
for installations with a large number of LDAP users. Please review the
[LDAP group sync benchmark metrics](#benchmarks) to see how
your installation compares before proceeding.
You can manually configure LDAP group sync times by setting the
following configuration values. The example below shows how to set group
sync to run once every 2 hours at the top of the hour.
**Omnibus installations**
1. Edit `/etc/gitlab/gitlab.rb`:
```ruby
gitlab_rails['ldap_group_sync_worker_cron'] = "0 */2 * * * *"
```
1. [Reconfigure GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure) for the changes to take effect.
**Source installations**
1. Edit `config/gitlab.yaml`:
```yaml
cron_jobs:
ldap_group_sync_worker_cron:
"*/30 * * * *"
```
1. [Restart GitLab](../restart_gitlab.md#installations-from-source) for the changes to take effect.
## External groups
> Introduced in GitLab Enterprise Edition Starter 8.9.
Using the `external_groups` setting will allow you to mark all users belonging
to these groups as [external users](../../user/permissions.md#external-users-core-only).
Group membership is checked periodically through the `LdapGroupSync` background
task.
**Omnibus configuration**
1. Edit `/etc/gitlab/gitlab.rb`:
```ruby
gitlab_rails['ldap_servers'] = YAML.load <<-EOS
main:
## snip...
##
## An array of CNs of groups containing users that should be considered external
##
## Ex. ['interns', 'contractors']
##
## Note: Not `cn=interns` or the full DN
##
external_groups: ['interns', 'contractors']
EOS
```
1. [Apply your changes to GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure).
**Source configuration**
1. Edit `config/gitlab.yaml`:
```yaml
production:
ldap:
servers:
main:
# snip...
external_groups: ['interns', 'contractors']
```
1. [Restart GitLab](../restart_gitlab.md#installations-from-source) for the changes to take effect.
## Group sync technical details
There is a lot going on with group sync 'under the hood'. This section
outlines what LDAP queries are executed and what behavior you can expect
from group sync.
Group member access will be downgraded from a higher level if their LDAP group
membership changes. For example, if a user has 'Owner' rights in a group and the
next group sync reveals they should only have 'Developer' privileges, their
access will be adjusted accordingly. The only exception is if the user is the
*last* owner in a group. Groups need at least one owner to fulfill
administrative duties.
### Supported LDAP group types/attributes
GitLab supports LDAP groups that use member attributes:
- `member`
- `submember`
- `uniquemember`
- `memberof`
- `memberuid`.
This means group sync supports, at least, LDAP groups with object class:
`groupOfNames`, `posixGroup`, and `groupOfUniqueNames`.
Other object classes should work fine as long as members
are defined as one of the mentioned attributes. This also means GitLab supports
Microsoft Active Directory, Apple Open Directory, Open LDAP, and 389 Server.
Other LDAP servers should work, too.
Active Directory also supports nested groups. Group sync will recursively
resolve membership if `active_directory: true` is set in the configuration file.
NOTE: **Note:**
Nested group membership will only be resolved if the nested group
also falls within the configured `group_base`. For example, if GitLab sees a
nested group with DN `cn=nested_group,ou=special_groups,dc=example,dc=com` but
the configured `group_base` is `ou=groups,dc=example,dc=com`, `cn=nested_group`
will be ignored.
### Queries
- Each LDAP group is queried a maximum of one time with base `group_base` and
filter `(cn=<cn_from_group_link>)`.
- If the LDAP group has the `memberuid` attribute, GitLab will execute another
LDAP query per member to obtain each user's full DN. These queries are
executed with base `base`, scope 'base object', and a filter depending on
whether `user_filter` is set. Filter may be `(uid=<uid_from_group>)` or a
joining of `user_filter`.
### Benchmarks
Group sync was written to be as performant as possible. Data is cached, database
queries are optimized, and LDAP queries are minimized. The last benchmark run
revealed the following metrics:
For 20000 LDAP users, 11000 LDAP groups and 1000 GitLab groups with 10
LDAP group links each:
- Initial sync (no existing members assigned in GitLab) took 1.8 hours
- Subsequent syncs (checking membership, no writes) took 15 minutes
These metrics are meant to provide a baseline and performance may vary based on
any number of factors. This was a pretty extreme benchmark and most instances will
not have near this many users or groups. Disk speed, database performance,

# LDAP
GitLab integrates with LDAP to support user authentication.
This integration works with most LDAP-compliant directory servers, including:
- Microsoft Active Directory
- Apple Open Directory
- Open LDAP
- 389 Server.
GitLab Enterprise Editions (EE) include enhanced integration,
including group membership syncing as well as multiple LDAP servers support.
For more details about EE-specific LDAP features, see the
[LDAP Enterprise Edition documentation](ldap-ee.md).
NOTE: **Note:**
The information on this page is relevant for both GitLab CE and EE.
## Overview
[LDAP](https://en.wikipedia.org/wiki/Lightweight_Directory_Access_Protocol)
stands for **Lightweight Directory Access Protocol**, which is a standard
application protocol for accessing and maintaining distributed directory
information services over an Internet Protocol (IP) network.
## Security
GitLab assumes that LDAP users:
- Are not able to change their LDAP `mail`, `email`, or `userPrincipalName` attribute.
An LDAP user who is allowed to change their email on the LDAP server can potentially
[take over any account](#enabling-ldap-sign-in-for-existing-gitlab-users)
on your GitLab server.
- Have unique email addresses, otherwise it is possible for LDAP users with the same
email address to share the same GitLab account.
We recommend against using LDAP integration if your LDAP users are
allowed to change their 'mail', 'email' or 'userPrincipalName' attribute on
the LDAP server or share email addresses.
### User deletion
If a user is deleted from the LDAP server, they will be blocked in GitLab as
well. Users will be immediately blocked from logging in. However, there is an
LDAP check cache time of one hour (see note) which means users that
are already logged in or are using Git over SSH will still be able to access
GitLab for up to one hour. Manually block the user in the GitLab Admin Area to
immediately block all access.
NOTE: **Note**:
GitLab Enterprise Edition Starter supports a
[configurable sync time](ldap-ee.md#adjusting-ldap-user-sync-schedule),
with a default of one hour.
## Git password authentication
LDAP-enabled users can always authenticate with Git using their GitLab username
or email and LDAP password, even if password authentication for Git is disabled
in the application settings.
## Google Secure LDAP **(CORE ONLY)**
> Introduced in GitLab 11.9.
[Google Cloud Identity](https://cloud.google.com/identity/) provides a Secure
LDAP service that can be configured with GitLab for authentication and group sync.
See [Google Secure LDAP](google_secure_ldap.md) for detailed configuration instructions.
## Configuration
NOTE: **Note**:
In GitLab Enterprise Edition Starter, you can configure multiple LDAP servers
to connect to one GitLab server.
For a complete guide on configuring LDAP with:
- GitLab Community Edition, see
[How to configure LDAP with GitLab CE](how_to_configure_ldap_gitlab_ce/index.md).
- Enterprise Editions, see
[How to configure LDAP with GitLab EE](how_to_configure_ldap_gitlab_ee/index.md). **(STARTER ONLY)**
To enable LDAP integration you need to add your LDAP server settings in
`/etc/gitlab/gitlab.rb` or `/home/git/gitlab/config/gitlab.yml` for Omnibus
GitLab and installations from source respectively.
There is a Rake task to check LDAP configuration. After configuring LDAP
using the documentation below, see [LDAP check Rake task](../raketasks/check.md#ldap-check)
for information on the LDAP check Rake task.
Prior to version 7.4, GitLab used a different syntax for configuring
LDAP integration. The old LDAP integration syntax still works but may be
removed in a future version. If your `gitlab.rb` or `gitlab.yml` file contains
LDAP settings in both the old syntax and the new syntax, only the __old__
syntax will be used by GitLab.
The configuration inside `gitlab_rails['ldap_servers']` below is sensitive to
incorrect indentation. Be sure to retain the indentation given in the example.
Copy/paste can sometimes cause problems.
NOTE: **Note:**
The `encryption` value `ssl` corresponds to 'Simple TLS' in the LDAP
library. `tls` corresponds to StartTLS, not to be confused with regular TLS.
Normally, if you specify `ssl` it will be on port 636, while `tls` (StartTLS)
would be on port 389. `plain` also operates on port 389.
NOTE: **Note:**
LDAP users must have an email address set, regardless of whether it is used to log in.

## For non AD servers it skips the AD specific queries.
## If your LDAP server is not AD, set this to false.
##

## - GitLab queries the LDAP server with 'jane.doe' and 'p@ssw0rd'.
##
## If you are using "uid: 'userPrincipalName'" on ActiveDirectory you need to

##
## LDAP attributes that GitLab will use to create an account for the LDAP user.
## The specified attribute can either be the attribute name as a string (e.g. 'mail'),

## Note that the user's LDAP login will always be the attribute specified as `uid` above.
##
attributes:
##
## The username will be used in paths for the user's own projects
## (like `gitlab.example.com/username/project`) and when mentioning
## them in issues, merge request and comments (like `@username`).
## If the attribute specified for `username` contains an email address,

## so that GitLab can remember which LDAP server a user belongs to.
#uswest2:
# label:
# host:
# ....
EOS
```
**Source configuration**
Use the same format as `gitlab_rails['ldap_servers']` for the contents under
`servers:` in the example below:
```yaml
production:
# snip...
ldap:
enabled: false
prevent_ldap_sign_in: false
servers:
##
## 'main' is the GitLab 'provider ID' of this LDAP server
##
main:
##
## A human-friendly name for your LDAP server. It is OK to change the label later,
## for instance if you find out it is too large to fit on the web page.
##
## Example: 'Paris' or 'Acme, Ltd.'
label: 'LDAP'
## snip...
```
## Using an LDAP filter to limit access to your GitLab server
If you want to limit all GitLab access to a subset of the LDAP users on your
LDAP server, the first step should be to narrow the configured `base`. However,
it is sometimes necessary to filter users further. In this case, you can set up
an LDAP user filter. The filter must comply with
[RFC 4515](https://tools.ietf.org/search/rfc4515).
**Omnibus configuration**
```ruby
gitlab_rails['ldap_servers'] = YAML.load <<-EOS
main:
# snip...
user_filter: '(employeeType=developer)'
EOS
```
**Source configuration**
```yaml
production:
ldap:
servers:
main:
# snip...
user_filter: '(employeeType=developer)'
```
Tip: If you want to limit access to the nested members of an Active Directory
group, you can use the following syntax:
```plaintext
(memberOf:1.2.840.113556.1.4.1941:=CN=My Group,DC=Example,DC=com)
```
Find more information about this "LDAP_MATCHING_RULE_IN_CHAIN" filter at
<https://docs.microsoft.com/en-us/windows/win32/adsi/search-filter-syntax>. Support for
nested members in the user filter should not be confused with
[group sync nested groups support](ldap-ee.md#supported-ldap-group-typesattributes). **(STARTER ONLY)**
Please note that GitLab does not support the custom filter syntax used by
OmniAuth LDAP.
### Escaping special characters
The `user_filter` DN can contain special characters. For example:
- A comma:
```plaintext
OU=GitLab, Inc,DC=gitlab,DC=com
```
- Open and close brackets:
```plaintext
OU=Gitlab (Inc),DC=gitlab,DC=com
```
These characters must be escaped as documented in
[RFC 4515](https://tools.ietf.org/search/rfc4515).
- Escape commas with `\2C`. For example:
```plaintext
OU=GitLab\2C Inc,DC=gitlab,DC=com
```
- Escape open and close brackets with `\28` and `\29`, respectively. For example:
```plaintext
OU=Gitlab \28Inc\29,DC=gitlab,DC=com
```
## Enabling LDAP sign-in for existing GitLab users
When a user signs in to GitLab with LDAP for the first time, and their LDAP
email address is the primary email address of an existing GitLab user, then
the LDAP DN will be associated with the existing user. If the LDAP email
attribute is not found in GitLab's database, a new user is created.
In other words, if an existing GitLab user wants to enable LDAP sign-in for
themselves, they should check that their GitLab email address matches their
LDAP email address, and then sign into GitLab via their LDAP credentials.
## Enabling LDAP username lowercase
Some LDAP servers, depending on their configurations, can return uppercase usernames.
This can lead to several confusing issues such as creating links or namespaces with uppercase names.
GitLab can automatically lowercase usernames provided by the LDAP server by enabling
the configuration option `lowercase_usernames`. By default, this configuration option is `false`.
**Omnibus configuration**
1. Edit `/etc/gitlab/gitlab.rb`:
```ruby
gitlab_rails['ldap_servers'] = YAML.load <<-EOS
main:
# snip...
lowercase_usernames: true
EOS
```
1. [Reconfigure GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure) for the changes to take effect.
**Source configuration**
1. Edit `config/gitlab.yaml`:
```yaml
production:
ldap:
servers:
main:
# snip...
lowercase_usernames: true
```
1. [Restart GitLab](../restart_gitlab.md#installations-from-source) for the changes to take effect.
## Disable LDAP web sign in
It can be useful to prevent using LDAP credentials through the web UI when
an alternative such as SAML is preferred. This allows LDAP to be used for group
sync, while also allowing your SAML identity provider to handle additional
checks like custom 2FA.
When LDAP web sign in is disabled, users will not see a **LDAP** tab on the sign in page.
This does not disable [using LDAP credentials for Git access](#git-password-authentication).
**Omnibus configuration**
1. Edit `/etc/gitlab/gitlab.rb`:
```ruby
gitlab_rails['prevent_ldap_sign_in'] = true
```
1. [Reconfigure GitLab](../restart_gitlab.md#omnibus-gitlab-reconfigure) for the changes to take effect.
**Source configuration**
1. Edit `config/gitlab.yaml`:
```yaml
production:
ldap:
prevent_ldap_sign_in: true
```
1. [Restart GitLab](../restart_gitlab.md#installations-from-source) for the changes to take effect.
## Encryption
### TLS Server Authentication
There are two encryption methods, `simple_tls` and `start_tls`.
For either encryption method, if setting `verify_certificates: false`, TLS
encryption is established with the LDAP server before any LDAP-protocol data is
exchanged but no validation of the LDAP server's SSL certificate is performed.
>**Note**: Before GitLab 9.5, `verify_certificates: false` is the default if
unspecified.
## Limitations
### TLS Client Authentication
Not implemented by `Net::LDAP`.
You should disable anonymous LDAP authentication and enable simple or SASL
authentication. The TLS client authentication setting in your LDAP server cannot
be mandatory and clients cannot be authenticated with the TLS protocol.

# Google Secure LDAP **(CORE ONLY)**
> [Introduced](https://gitlab.com/gitlab-org/gitlab-foss/issues/46391) in GitLab 11.9.
[Google Cloud Identity](https://cloud.google.com/identity/) provides a Secure
LDAP service that can be configured with GitLab for authentication and group sync.
Secure LDAP requires a slightly different configuration than standard LDAP servers.
The steps below cover:
- Configuring the Secure LDAP Client in the Google Admin console.
- Required GitLab configuration.
## Configuring Google LDAP client
1. Navigate to <https://admin.google.com/Dashboard> and sign in as a GSuite domain administrator.
1. Go to **Apps > LDAP > Add Client**.
1. Provide an `LDAP client name` and an optional `Description`. Any descriptive
values are acceptable. For example, the name could be 'GitLab' and the
description could be 'GitLab LDAP Client'. Click the **Continue** button.
![Add LDAP Client Step 1](img/google_secure_ldap_add_step_1.png)
1. Set **Access Permission** according to your needs. You must choose either
'Entire domain (GitLab)' or 'Selected organizational units' for both 'Verify user
credentials' and 'Read user information'. Select 'Add LDAP Client'
TIP: **Tip:** If you plan to use GitLab [LDAP Group Sync](index.md#group-sync-starter-only)
, turn on 'Read group information'.
![Add LDAP Client Step 2](img/google_secure_ldap_add_step_2.png)
1. Download the generated certificate. This is required for GitLab to
communicate with the Google Secure LDAP service. Save the downloaded certificates
for later use. After downloading, click the **Continue to Client Details** button.
1. Expand the **Service Status** section and turn the LDAP client 'ON for everyone'.
After selecting 'Save', click on the 'Service Status' bar again to collapse
and return to the rest of the settings.
1. Expand the **Authentication** section and choose 'Generate New Credentials'.
Copy/note these credentials for later use. After selecting 'Close', click
on the 'Authentication' bar again to collapse and return to the rest of the settings.
Now the Google Secure LDAP Client configuration is finished. The screenshot below
shows an example of the final settings. Continue on to configure GitLab.
![LDAP Client Settings](img/google_secure_ldap_client_settings.png)
## Configuring GitLab
Edit GitLab configuration, inserting the access credentials and certificate
obtained earlier.
The following are the configuration keys that need to be modified using the
values obtained during the LDAP client configuration earlier:
- `bind_dn`: The access credentials username
- `password`: The access credentials password
- `cert`: The `.crt` file text from the downloaded certificate bundle
- `key`: The `.key` file text from the downloaded certificate bundle
**For Omnibus installations**
1. Edit `/etc/gitlab/gitlab.rb`:
```ruby
gitlab_rails['ldap_enabled'] = true
gitlab_rails['ldap_servers'] = YAML.load <<-EOS # remember to close this block with 'EOS' below
main: # 'main' is the GitLab 'provider ID' of this LDAP server
label: 'Google Secure LDAP'
host: 'ldap.google.com'
port: 636
uid: 'uid'
bind_dn: 'DizzyHorse'
password: 'd6V5H8nhMUW9AuDP25abXeLd'
encryption: 'simple_tls'
verify_certificates: true

<!-- ## Troubleshooting
Include any troubleshooting steps that you can foresee. If you know beforehand what issues
one might have when setting this up, or when something is changed, or on upgrading, it's
important to describe those, too. Think of things that may go wrong and include them here.
This is important to minimize requests for support, and to avoid doc comments with
questions that you know someone might ask.
Each scenario can be a third-level heading, e.g. `### Getting error message X`.
If you have none to add when creating a doc, leave this section in place
but commented out to help encourage others to add to it in the future. -->
