Managing the Participant Cache
To improve the access time required for users, groups, and organizations, Windchill maintains an internal participant cache of all user, group, and organization information that has been obtained from the Windchill database and directory services.
* 
If user, group, or organization attributes are changed using an administration tool other than the Participant Administration utility (for example, using a directory administration tool), then the cache entries containing those attributes must be removed for Windchill to display the changed attributes.
You can manage the participant cache in two ways:
By setting the maximum time that the information about a participant can remain available in the cache. Then, cache entries are automatically removed when participants try to access the old entries.
By selecting actions that remove information from the cache.
