Gitlab-CI Login Faliure

I am attempting to switch from another CI product to Gitlab-CI but I am having trouble logging in using Gitlab (I am using LDAP to login to Gitlab-CE).

When I select “login using gitlab” I get the following error:

“Client authentication failed due to unknown client, no client authentication included, or unsupported authentication method.”

Is it possible to login to GItlab-CI using LDAP in Gitlab-CE? If so, what error logs should I be looking at to resolve this issue?
