Description (partial)


In some situation the radius accounting packet won't include the Class attribute.
The main consequence is that it will break a deployment with NAC single sign on as NAC need that AV pair to discriminate user group.
if you are using NAC with SSO, you will find the user mapped to the default role instead than to the correct one every time this condition is met.


Client first associate then goes in standby.
Next association after stanby will fire an Accounting packet without Class AV.
