[Deploying Sakai] create limited admin workspace, limit admin functionality

[Kurosch Petzold]

Hello,

is there a way to create limited permission admin roles or create a second
admin workspace with limited number of tools.
If neither of them works, could anyone who has/had this problem at their
institution/university/company explain to me how they solved it (if there
is a solution to it at all).

Or to get more to the fact of the actual problem is there a way to use
sakai.sites without su?

Best regards,
