- Check if a user is a mapped group.
-
- This function will check if the group SID is mapped onto a
- system managed gid or onto a winbind manged sid.
- In the first case it will be threated like a mapped group
- and the backend should take the member list with a getgrgid
- and ignore any user that have been possibly set into the group
- object.
-
- In the second case, the group is a fully SAM managed group
- served back to the system through winbind. In this case the
- members of a Local group are "unrolled" to cope with the fact
- that unix cannot contain groups inside groups.
- The backend MUST never call any getgr* / getpw* function or
- loops with winbind may happen.
