Delegate Management of a Group or Role

To delegate management to someone who does not have user administration capabilities, use explicit (white) or ACT (green) grants of the WriteMetadata permission. For example, to delegate management of a group named ETL Developers to a user named Tara, you would access the Authorization tab for the ETL Developers group, add Tara, and explicitly grant the WriteMetadata permission to her.
Note: Do not assume that someone who has only indirect (gray) settings on someone else's Authorization tab has not been delegated management. The best way to check for delegation of an identity is to check each entry in the Users and Groups list box on that identity's Authorization tab to see whether there are any explicit (white) or ACT (green) grants of the WriteMetadata permission.
