configuration for realm with prefix and suffix

[Mike Cisar]

Running FreeRADIUS 1.1.3, usernames are in 'username' format in a unix
passwd file.  Our dialup users are proxied to us in 'username at suffix.com'
format and to this point everything has been working just fine.

Now the tougher part... We've gained access to some additional POPs and
although the suffix is the same, we are proxied these with a prefix as
well... so what we get is in the form  prefix/username at suffix.com   I'm
having trouble wrapping my head around how to configure our server to deal
with these.

Any thoughts or pointers are appreciated.

Cheers,
