Having a really weird issue over here with NAC and 802.1X.

I can see client requests coming in, I've set up a rule to allow access but for some reason I get the following;

There is no method to authenticate the user DBDF207C-5A08-4333-BAC8-8404E41AD076 discarding request.

I'm also seeing "NAC System Misconfigured" but can't for the life of me figure out why/where. 

Any pointers on where to start?

To post the resolution: 

The error message "NAC system misconfigured" is due to an incomplete AAA configuration. The AAA configuration must be configured to in order to determine how authentications will be processed. If an 802.1x authentication is received by NAC Manager and there is not RADIUS server defined in a basic AAA configuration, or no specific configuration rule in the advanced AAA configuration this error message will be seen.
