When hosting several teams, I discovered that (at least by default) users in different teams can see users from other teams.
I didn’t find any relevant setting in the docs, so I imagine it would be a new feature: letting the admin configure whether or not team isolation is activated.
That’s what I meant, yes. It means that I cannot host several projects on a gitlab+mattermost server if I don’t want people from one project to interact with people from another one. Is it structurally unavoidable?
