Not sure if this what you are asking since if a user is not authenticated access is denied but here goes...
For our access network when an unknown user if presented we accept and forward the session to a walled garden website that says
Your username is incorrectly set, please check your configuration parameters
Because most will just try changing the password if they get an authentication failure , not seeing username and uesrname are diferent...
