ACS SE 4.0 and EAP-TLS authentication

Hi there,

I have configured an ACS SE (v4.0) to use EAP-TLS authentication. The client is XP SP2 tablet running Intel wireless Pro drivers. When I try to connect to the wireless network I get Authentication failed due to invalid user credentials  but nothing gets logged onto the ACS failed authentication logs.  I also have the Unknown user policy enabled and the global authentication setup configured to do EAP-TLS auth on the ACS..has anyone come across this error message?At the mo I cant test using the Windows supplicant thanx to SOE lockdown!

You need to makes sure on the ACS you have enabled logging for failed and passed authentication, what is the NAS device, make sure on the NAS your authentication server is configured properly and it is reachable. it is also good run a packet caputre or look at package.cab to make sure that the packets are reaching the ACS

I ended up upgrading to v4.2 because of a Cisco bug -CSCsg62438. All is now working fine
