You configure the Symantec Endpoint Protection Manager to collect user information (Admin > Install Packages > Tasks, click Set User Information Collection). The clients receive the request to enter information and submit it, but this information never appears in the Clients tab, under the clients' properties.
No errors are reported, and communication debug logs indicate the information is being sent from the client to the Symantec Endpoint Protection Manager.
The User Information collection feature does not work with localized clients.
This is working as designed.
