Enable fine-grained logging for LDAP-issues


I’m trying to set up a new GitLab instance, hooking it up a FreeIPA. After some fiddling, I managed to verify correct LDAP handshake using wireshark. A user (that is visible from the GitLab admin user) is even created correctly. However, when I attempt to log in, all I get is “Access denied for your LDAP account.”

I would like some advice on how to enable further log messages to see what is going on.
