Require realm suffix

[Ben Thompson]

Hi

I have set up FreeRADIUS so that I am using the relam format
username at suffix. I have succesfully got this working by adding the
relevent realm to proxy.conf and setting authhost and acchost to LOCAL.
Currently when someone logs without specifying a realm, they are still
authenticated and I would like to know if it is possible to change this
behavoir so that users must specify the realm suffix.

Thanks
