To set User object properties, uses must have ALTE ANY USER permission on the database or be a member of the db_owner fixed database role.
To change the default schema, users must have ALTER permission on the specified user or be the owner of the user.
To create or drop a user, users must have ALTER ANY USER permission on the fixed server role or be a member of the db_owner fixed database role.
To grant, deny, or revoke permission on the specified user to other users, users must have CONTROL permission on the specified user.
