I'm currently running a Cisco ACS v3.2 on a windows server 2003 Pro with a safeword token server. I'm using PEAP (EAP-GTC). The problem is my client(Windows xp Pro SP2) gets disconnected 1 or 2 minutes after he connects to the access point. I have no idea of where the problem could be. I've put PEAP session timeout to 120.
Did you ever find an answer to this problem? We have recently begun experiencing this on several of our clients running EAP-TLS:
We receive the same message in our logs:
Authen session timed out: Challenge not provided by client
The strange thing is that these clients will work for a while, then disconnect, and then reconnect. Causing the users to lose network access. To me it looks like a timeout problem where the client does not respond in a timely manner to the challenge.
