Starting from System Manager Release 6.3.8, when you create a role with access to User Management, you can restrict the access to the Administrative Users page.
The roles that are created earlier than Release 6.3.8 with permissions to access User Management can access the Administrative Users page by default. The roles continue to have permission after the upgrade to Release 6.3.8 or later. To restrict access to the Administrative Users page, clear the Allow access to Administrative Users Web UI check box on the Permission Mapping page.
To gain access to the Administrative Users page, log on to the System Manager web console and click the link. The Administrative Users page displays the list of administrative users that are available in the system. By default, when you add user-related permissions to a role, the system selects the Allow access to Administrative Users Web UI permission.
