  It's not the RADIUS protocol doing that, it's the implementation.

  The issue is that one of the authorization parameters is which
authentication methods you are allowed to use.  So the control flow
should really go like:

  authorize which authentication type
  do authentication
  if authenticated, give additional authorization.
