Trying to authenticate Windows Vista computers with machine certificate and EAP-TLS on the wired network. Sometimes one or two computers fail the authentication when it boot and it is not allways the same computers. On the wireless network everything works fine.
The certificate has enrolled to the computers and a GPO is puched out with the 802.1x settings.
The switch it connects to is a 3560v2 running 15.0(2)SE4.
In the ISE loggs it looks like the computers try to authenticate with it's hostname and not certificate. I see this error: 5440 Endpoint abandoned EAP session and started new.
And in the log it say:
Prepared EAP-Request proposing EAP-TLS with challenge
Valid EAP-Key-Name attribute received
Returned RADIUS Access-Challenge
Received RADIUS Access-Request
RADIUS is re-using an existing session
Extracted EAP-Response/NAK requesting to use PEAP instead
Prepared EAP-Request proposing PEAP with challenge
In the Windows error log I see. Event ID 15514 The authentication failed because there is a problem with the user account.
I have now set Max Authentication Falures to 3 in windows but it does not solve the problem, only works around it some times.
Has anyone seen these behavior? What has your solution been?
