Hi,

We want to integrate the WLC with ACS 4.1 using EAP FAST authentication. As of now, it is working fine with ACS 3.3.

WLC side, I have configured the new Radius server & pointed it in WLAN ID

In ACS 4.1, I have configured as per the below doc.

But It is not working & I am seeing the failed attempt logs with the Error message as

"Invalid message authenticator in EAP request"

Need your help on this to solve this problem.

Regards,

Guru
