When Mattermost is installed with GitLab and uses GitLab SSO, I wonder how we could integrate with bots. In my use case, webhooks are no option because the outgoing webhooks are not available for private channels. So I wanted to use a bot that uses the API and therefore should login as a bot user to Mattermost. But that doesn’t seem possible when SSO with Gitlab is enabled. Is there something I’m missing?
Found the answer. You need to create a user from the CLI which is not a SSO user:
cd /opt/gitlab/embedded/service/mattermost/i18n
sudo -u mattermost /opt/gitlab/embedded/bin/mattermost -config="/var/opt/gitlab/mattermost/config.json" -create_user -team_name="name" -email="user@example.com" -password="mypassword"
I was wondering if you were able to solve how to get a [session token] for a user where mattermost is set-up as part of gitlab. Given that authentication is happening against gitlab, it seems the mattermost user lacks a ‘password’ to pass for logging in via the mattermost API and therefore gets rejected.
I asked over here … a related question … and added more detail there.
Thanks.
@mccoole I got it working with an explicitly created user for Mattermost as described above. As that is working just fine, I’ve never followed up on this issue trying anything else.
