Groups in any domain can be created by the Server Administrator if the administrator account has the Can Modify All Accounts And Domain Settings access right.
A Domain Administrator can create, remove, and rename groups only if the CanCreateGroups access right is granted to the administrator account.
To create a new group, type a new group name into the field on the right side of the Create Group button.
Click the Create Group button. When a new group is created, its name appears in the list. The Server automatically displays the Settings page for the new group.
To specify Group Settings, click the group name in the Accounts list. The Group Settings page appears.
If a Group Member is a name of an Account, or some other Group in the same Domain, then the Group Member list is automatically updated if that Account or Group is renamed or removed.
If you want to rename a Group, open its Settings page with a Web browser, and enter a new Group name into the New Group Name field. Click the Rename Group button.
If there is no other object with the same name as the specified new Group name, the Group is renamed and its Group Settings page should reappear on the screen under the new name.
If you want to remove a Group, open its Settings page with a Web browser, and click the Remove Group button.
