I configured freeradius on a Fedora Core 6 machine to use PAP against a cisco switch radtest on localhost is successfully. I think radiusd.conf users and clients.conf files are ok

From the cisco device after I insert user and password telnetting to it I got:

Sleeping until we see a request. I can't figure out what's wrong... It's seems that something missing on the cisco side Is right that radius send back Access-Accept on port 21645? Thanks in advance
