Managing user groups
You can specify exceptions to user group properties by changing the properties for a single user account after you add that user account to the user group. If you change and reapply the user group properties, the updated group properties override any previous exceptions in the properties of user accounts.
If you move a user account out of a user group, the user account remains in the global users list, but it does not appear in the user group lists.
