GitLab does not support Microsoft Active Directory Trusts - workarounds

Problem to solve

I am using self hosted Gitlab 17.3.
I have working integration with LDAP.
Now my company would like to give access to some external consultants, which are in a different AD domain.
My primary base domain:
base: ‘OU=XXX,DC=baz,DC=foo, DC=bar’

My other domain which is configured with MS AD trust:
base: ‘OU=XXX,DC=baz,DC=foo2, DC=bar’

I see Gitlab documentation
Integrate LDAP with GitLab | GitLab
where is says: GitLab does not support [Microsoft Active Directory Trusts]

My question is, if there is some good workaround for this situation.
For example I see that in Premium, there is possibility of Secondary Ldap server:
Integrate LDAP with GitLab | GitLab

Could this secondary server use this other domain as base parameter?

Yes, the premium version would allow you to configure both domains. Your other alternative, would be to add them to a group on the first server that is already configured rather than use the second domain, but obviously you have a reason for not configuring external users in that first domain.
