Bug: Password reset and LocalPasswordSync don't always play nice with multiple domains

Requiring a user to reset their password on next login and attempting to sync the local password can get into an unsynced state.

This may be more complicated and require a machine bound to domain but NoMAD working with a different domain.

changed title from Bug: Password reset and LocalPasswordSync don't always play nice to Bug: Password reset and LocalPasswordSync don't always play nice with multiple domains

changed milestone to %V. 1.1

Should be addressed at the same time as #139 as NoMAD will be more aware of the realm of the currently logged in user.
