While testing authentication with a Motorola Canopy AP I noticed that I was getting a Certificate Compatibility warning. I understand why this typically happens. What struck me as odd is that network entry still succeeds. Just to verify nothing really out of the ordinary was happening I verified the CA certificate that the server was using and re-imported this certificate onto the device, but still receive the same notification and still the same successful network entry. Does FR only use the State attribute to determine if the previous session didn't complete? The reason I ask is that the State attribute sent by FR in the Access-Challenge, and then echoed in the following Access-Request are the same, but the warning appears to truncate the value.

I'm a little confused as to what is really happening here. Ben
