You can add authentication servers and enable remote authentication on the management server to enable remote users within the authentication server to access Performance Manager.
You must have enabled remote authentication and configured your authentication service so that the management server can authenticate remote users or groups in the authentication server.
If the authentication server that you are adding is part of a high-availability pair (using the same database), you can also add the partner authentication server. This enables the management server to communicate with the partner when one of the authentication servers is unreachable.
Perform a test authentication to confirm that you are able to authenticate users in the authentication server that you added.
