@it33 I’ve done some test, here we go!
I’m using Mattermost standalone on a different server, not using GitLab’s version. To configure it, I’ve used the instruction you linked.
After download the new image, so a complete new installation, I’ve configured Mattermost for GitLab integration. Then I created a Team but was possible only with Email Sign up, so I did. Once created a team I logged out and:
- In the login for Team (
<mattermost_addres>/<team>
) there is a link for GitLab but I getWe couldn't find the existing account
error, I can login only using Email and password; - In the Main page, I can create a New Team only using Email Signup, no GitLab options are present
To add members to my team, since email is still not working, I sent them the Team Invite Link. This allow them to get to Team Page, login using GitLab link, create a user and join the channel. After that they can always join using GitLab authentication. They can’t join using GitLab if I don’t send them the Invite Link (as expected I think).
I’ve never saw the GitLab button presented before but saw something when my mates do after the clicking the Team Invite Link. Let me know if I can try something else or give you more info about it.
