Certificate Compatibility - Successful Network Entry

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

This appears to be a client side issue, but I would like to confirm
that this is the case. I'm a little confused as to what is really
happening here.
