Users Groups

Hi everyone. I'm using FreeRADIUS Version 2.1.1, I use it to control the access to a routers networks. I want to permit certain users to get access to some routers and deny access to another routers. Like group the users per routers, I read some documentation, but i can't make it work. Thanks in advance. _________________________________________________________________ Hotmail: Free, trusted and rich email service. https://signup.live.com/signup.aspx?id=60969
