This seems like a silly question, but I can't find the solution myself and not on the web.
I need to find out which groups a user is a member of. (Similar to the "Member Of" tab in active directory) Where can I find that?
P.S. I'm trying to solve a more general issue, that how can I find out what a certain user has access to. I'm trying to grant permissions only through groups to solve this, but I couldn't find group memberships either. Any other ways I can achieve this?
Note that my scope is only one site collection.
