Docs: document the difference between the admin user and the server admin
Type of issue
There are 2 types of GitLab admin users:
- "Admin user": the user who has admin permissions for a given GL instance. Logs into the instance via UI and has access to the admin area.
- "Server admin": the user who has access to the instance administration via server. Has access to
gitlab.rband other admin files not accessible from the UI.
Problem to solve
Document the difference between the users, clarify who has access to what.
