[Ozan Oguz]

Hi everybody,

We are trying to authenticate wireless clients using radius server and 802.1x protocol. Client wireless interface status remains "Validating Idenitity" and IAS server giving the following error :

An Access-Request message was received from RADIUS client WLAN_CONTROLLER_TEST with a message authenticator attribute that is not valid.

Best Regards

Generally this means the NAS key does not match.  I tend to put the key into a notepad and cut and paste into both the AAA and WLC
