This configuration parameter specifies whether to index user principle names (UPNs) that are stored in the Centrify user cache. You can use this parameter to differentiate between two users when the UPN of one user is equal to the SAM@domain_name of another user, and both user objects are stored in the user cache.

To enable UPN indexing, set this parameter to true. For example:

adclient.cache.upn.index: true

By default, this parameter is set to false, and UPNs are not indexed.
