Use this tab to view or modify the administrative roles of the user you selected.
Provide roles for this user to assume by placing each role name in the Assigned Roles column. When users assume a role, they relinquish the properties of their own user account and take on the properties of the role -- including the rights, home directory, password and so forth. You can think of root as a role with all rights; other roles have more limited rights.
For more information about each role, view the role's properties in the Administrative Roles tool.
