Mattermost needs LDAP authentification

[stephdl]

Proposed solution

All modern authentication are LDAP based but mattermost offers this feature only for the enterprise version
However gitlab allows to use a SSO to authenticate in mattermost, however gitlab is a bit heavier to only authenticate.

We could use https://github.com/Crivaledaz/Mattermost-LDAP

The LDAP authentication ask for a mail field in the LDAP that is a mandatory, actually we do not have it inside LDAP

Alternative solutions

still continue to use the SQL authentication

Still discussing on it, no worries

This issue is postponed: we'll discuss it again after milestone 8.2.

Actually we're missing the management of the mail LDAP attribute, required by the plugin to work correctly. It requires some user-portal work that is not planned for now.
