Conditional Proxy Radius

[Abdul Qadir <ablqadir@yahoo.com>]

HI,

    I am using freeradius with SER. In simple words i want to proxy radius based on user id instead of realm. Also want to add some extra functionality before I do the proxy.  My requirements are as follows

I have two different types of users. Some users have numeric user id and some have Alphanumeric. E.g 
123456@mydomain.com 
and 
abdefghijk@mydomain.com

I would like to configure my radius server as

1. If user id is numeric. i.e 123456@mydomain.com
    Query local database for authentication.

2. If user id is alphanumeric i.e abdefghijk@mydomain.com
    2.1 First Query local database to get new realm value for this user id. eg. database query will return me abdefghijk@RemoteDomain.com
    2.3 Proxy the new URI to another radius.


Please suggest whether its possible to do so, if yes what is the procedure. And which version of FreeRadius
 support this kind of functionality.

Thanking you in advance.

Best Regards,
Abdul Qadir
