Add Option to map user to admin group

[bokkabonga]

I got everything to work so far. However I fail to map certain roles in keycloak to the nextcloud admin group.

I tried creating a realm role "admin" (which I´d like to avoid) and assigned it to users, i also created a client role "admin". Both didn´t work.

I have a group whitelist regex in place, to which i added the admin group in case it would cause any problems. Has anyone ever got this to work properly? I found some older Issues but nothing really helped for me...
