Is there some way to use CLID (Calling-Station-Id attribute) to determine wich server to proxy access-request to?
Do not ask why not using realms. We do use realms too.
But the only way to validate that the user comes from our network is to check his CLID. Because everybody can set any realm in his login credentials. CLID, also known as IMSI in CDMA packet data, is in the form of 15 digits XXXXXXXXXXXXXXX. A few starting digits (say first six ones) identify our network. If this first digits are different from ours, that means the access request should be sent to another operator's AAA server.
