Mattermost-server: Changing mattermost username from gitlab provider.

[meshaabi]

Summary

Changing gitlab username after a fresh gitlab-omnibus installation (working SSO) does not change the username in mattermost.

Steps to reproduce

1. My original username is User1

2. Change account username to user2 in gitlab.

   Expected behavior

3. Username also changes to user2 in the mattermost instance.

   Observed behavior

4. Username remains the same in mattermost (user1), white both username and user URL have been updated in gitlab.

5. Trying to change it within mattermost gives you the following message

This field is handled through your login provider. If you want to change it, you need to do so through your login provider.

Possible fixes

If you can, link to the line of code that might be responsible for the problem

Wondering if it's an incorrect setup here or there's anyone else facing the same issue.

Thanks!

@hackfanatic Thanks for the report!

Does the username get updated if you log out from Mattermost, then log back in?

[jasonblais]

We haven't received an update so we will assume that the problem is fixed or is no longer valid.

If you still experience the same problem, try upgrading to the latest version.

If the issue persists, please reopen this issue with the relevant information and we'd be happy to investigate it further.

Hi @jasonblais , Sorry I missed the notifications to these messages.

Updated to latest gitlab omnibus package,

• Logged out in both mattermost and gitlab instances
• Logged into gitlab, changed username
• Logged into mattermost and still have my original username from the initial setup moment.

Though think the mattermost version in the omnibus package though isn't the latest one so I'll revisit this ticket and let you know if this persists after the next update.

Thanks for writing 👍

I've hit this, currently using gitlab omnibus 8.13.3. Change the username in gitlab, log out and back in (to both) has no change.

Sorry for my incredibly long delay here.

Created a Jira ticket here, which will be triaged on Monday. https://mattermost.atlassian.net/browse/PLT-4844

Reopened this GitHub issue in the meantime

Ran into this in Omnibus GitLab 8.14.1 as well
