Purge-Cache
The Purge-Cache webject purges user and group objects from the Windchill participant cache.
The Windchill cache of users and groups optimizes performance by minimizing the number of requests it needs to make of the LDAP directory service.
When LDAP entries defining Windchill users or groups are modified directly without using the Participant Administration utility, then information in the cache can become outdated.
Use the Purge-Cache webject to purge outdated entries from the cache and force Windchill to re-retrieve them from the LDAP directory service.
* 
If you are purging all entries at once (without specifying DIRECTORY_REF or OBJECT_REF) from the Windchill participant cache, then only a Windchill administrative user can execute the webject.
If you are purging a few individual entries from the Windchill principal cache, then a user with write permission to those entries can execute the webject.
