Is there a way to look up if an user-id is being used on Viprion

Hi, we've taken over the support for a Viprion 2400 that has 8 vCMPs Guests carved up on it. The guests are running LTMs and APMs. We've received a notification from the security folks asking us about the usage of the 2 user-id's that had been created specifically for the 2 factor authentication for the apps being load balanced on the vCPM Guests.

Is there a way to identify those 2 id's as we haven't been able to find them in access policies or any place else. We're also running Big-IQ, but have not found the way to search for these user-ids.

Thanks.
