When using the radius monitor should the F5 accept the access-reject message as a successful response to the monitor?

documentation says: "Checks the status of Remote Access Dial-in User Service (RADIUS) servers. The check is successful if the server authenticates the requesting user. A RADIUS monitor requires a user name, a password, and a shared secret string for the code number."

i read that as you need a successful authentication, but i can't find it clearer then here.
