You can determine which users are permitted to access a Performance Dashboard.
The specified user name is used both for the login and to allow access to selected Performance Dashboards.
Login
You can specify any user name to log in to a Performance Dashboard. The data is immediately verified against the source system specified in the jaas configuration.
Access authorization
For each Performance Dashboard, you must specify users and/or user groups that are permitted to view the dashboard. Once logged in, users will see only those Performance Dashboards for which they have access authorization, either directly or through membership of a particular group. Every user listed in the <userlist> XML element and every user group is assigned to a particular source system by the source attribute (default ppm).
