More debugging makes me suspect the AP is not handling the NAK properly.
Two different AC AP had same issue, so either they are both broken
similarly, or perhaps there is something wrong with the NAK message.

Our system works internally because it never even tries MD5, just goes
straight to AKA.  Seems to be no good way to make the user's radiusd
do the same.

We'll try yet more APs to see if we can find one that works.

Thanks,
Ben
