Hi @ahmaddanial, here’s some information on the setup:
- The users are not deactivated/blocked in GitLab.
- The users can access GitLab just fine and their sessions are also preserved so they don’t have to login each morning.
- The issue appears only in Mattermost.
- The users also do not have this issue with pure AD authentication.
- We are only 2 users with System Admin permission in Mattermost and only I am actively administering it (I’ve checked :)) so nobody is deactivating the users manually.
- There is no custom automation added at any step between GitLab and Mattermost.
- We have started experiencing this issue in the past 6 months, there were no such problems before that. We haven’t really changed anything related to Mattermost in that time.
- I upgraded the Mattermost server 2 months ago from 5.5.0 to 5.25.4 (following the docs strictly) but I can verify that the issue started before that.
@XxLilBoPeepsxX For it to be happening only on the A-B users and not All users, I’m thinking something like session house-keeping or database-related. If it was transport / proxy I would expect it to be affecting more people with random names.
