I just upgraded a small instance with 3 teams from 2.x to 3.0.2. The instance has email signups and logins disabled, but has a Gitlab integration so that all users could login using their respective Gitlab accounts.
After the upgrade, after clicking on the “login with Gitlab” button, all I get is this message:
An existing user is already attached to your gitlab account
Where do I even go from here? Of course there is an existing user using my Gitlab account, that’s what I’m trying to login to! There doesn’t seem to be any useful info in the logs nor is there anywhere to go from that message. Since none of the original accounts even had passwords (since they were Gitlab logins) I don’t want to make everybody reset passwords and manage them separately from Gitlab. How can I get these wired up again so they can login?
