Hi I need some opinions. Condition: 1. I have a local realm (suffix), xyz.com. I'm using freeradius 2.1.3+mysql. 2. My own user's username in mysql radcheck table is store in username@xyz.com format 3. A person want me to proxy his prefix ABC/his-customer-username@myrealm to his radius server, i.e: ABC/his-customer-username@xyz.com 4. The proxy has strip both prefix and suffix, which means when ABC/his-customer-username@xyz.com auth request come in, i have to forward only his-customer-username to his radius. I know i can using hint to strip his prefix, but i'm stuck at proxy config. I can't proxy xyz.com to his radius, otherwise my own user's username will also proxy to his radius server. How can i proxy his-customer-username without mess up my own user's username? It's sound a bit stupid, but i still keen to find out is that possible to achieve the objective or not. Thanks a lot!!
