About OpsCenter AT
Veritas Product Authentication Service (VxAT), which consists of Root Broker and Authentication Broker, is no longer a shared component and is installed along with OpsCenter server. This authentication service is very specific to OpsCenter and therefore, it is called OpsCenter AT.
Note:
No other product can use OpsCenter AT for user authentication.
In a clustered OpsCenter setup, each cluster node has an embedded AT binary. All cluster nodes share the same AT configuration and the authentication data exists on a shared disk.
Name of the OpsCenter Authentication Service is ops_atd.
