proxying users

[Maqbool Hashim]

Hi,

Is there a way that I can get my proxying radius server to append the 
realm for certain users.  Basically I'm wondering if theres a way of 
having a realm based server where users don't have to type in the realm 
as part of their username.  I'm wondering if I can get the radius server 
to do it as part of its processing before it proxies the access request.

Thanks
