to using SIDs instead of RIDs. The new funciton sid_peek_check_rid() takes an 'expected domain sid' argument. The idea here is to prevent mistakes where the SID is implict, but isn't the same one that we have in the struct. Andrew Bartlett (This used to be commit 04f9a8ff4c7982f6597c0f6748f85d66d4784901)
