I\'ve just setup gitlab, but I\'m completely lost with regards to admin user. The wiki seems silent about this topic, and google hasn\'t been of help either.
So, how do
There is a check box on web interface, if your GitLab username has admin access.
Login to GitLab, and in the context of Admin Area > Users > the.other.user > edit > Access > Access level
, check "Admin".
I didn't try the Linux commands, because web GUI is more reliable. The official GitLab document about permission didn't include this setting, maybe it feels like intuitive.
