Setting a realm in the User-Name based on Client-IP-Address

[Jason E. Murray]

I have quite a few people on campus who authenticate to various systems
without using a realm in their username.  With our current radius server
there is a option in the clients file where you specify a Default-Realm
per client.  When an authentication request comes in from this client
the @realm is automatically tacked onto the User-Name attribute then
proxying is done based username at realm combination.

I need to replicate this behavior in FreeRadius.


In the users file I have: 

DEFAULT Client-IP-Address == 127.0.0.1, User-Name !~ ".*@.*", Proxy-To-Realm := "rts"
        Fall-Through = Yes

In the preproxy_users file I have:

DEFAULT Client-IP-Address == 127.0.0.1, User-Name !~ ".*@.*"
        User-Name := "%{User-Name}@rts"

Both of these lines check to see if the @realm is missing and the
Client-IP-Address is 127.0.0.1 the proxy and rewrite accordingly.

My question is there a better way to do this, this seems a bit kludgy.


Using FreeRadius 1.1.4

Thanks in advance,
