net-ldap version update

There is a bug in net-ldap < 0.5.0 preventing connections to Microsoft servers. Pushing the net-ldap dependency version should fix it. See the following net-ldap issue for a description.

Can you please tell me what to do to get this included (or at least patched for my local install) in the community version of gitlab?
