Users and User Groups
The Users and User Groups tabs list the user IDs and the user groups that are stored on the portal server.
After you select a user or user group from one of the lists, you can click any of the tabs in the lower half of the window to see the what permissions have been granted and what has been assigned. User groups enable the administrator to authorize the same set of functional permissions, applications, and Navigator views to multiple users at one time. Management of user authorization can be done by groups as well as individually. A user can be associated with one or more user groups; authorization by group will be by inclusion and not exclusion (nested groups are supported). Authorization will also be by global authority and by association with managed system and managed system lists. This security is not dependent on external authorization.
