SSO/LDAP for Mattermost
Inspired by #849 (closed)
Native LDAP integration is a MatterMost Enterprise Edition feature.
However it seems like there are some possible workarounds which could be investigated:

Used this for a client for AD Auth on MM5 "Team" - it works - it's a little fragile sometimes - but better than paying for EE for one feature.
May be worth watching - but it looks like it may have issues with newer MM versions. https://github.com/Crivaledaz/Mattermost-LDAP/issues/25
The other route could be to delegate MM authentication to GitLab (Built into GL/MM) and let GL to the LDAP stuff. I'll try building out this scenario in a Lab and report back. What is C.O using to hold user records (Drupal? CiviCRM? LDAP server?)
