It's working fine, thanks again tarnold.
One more question, in my syslog, here is what I get as message :
10-03-201309:11:35Local1.Debug10.1.1.32013-10-03 09:11:32,680 10.1.0.3 Guest Access 3 1 0 RADIUS.Auth-Method=PAP,RADIUS.Auth-Source=Local:localhost,
As you can message, it's missing information in the message (RADIUS.), any idea why ?
