Problem with Freeradius and WiMAX

[Kristoffer Milligan]

Good day list

This is my first post to the list, so let me open by congratulating on a
great piece of software. I'm impressed.

I have the pleasure of working with WiMAX and a system called 4motion.
We have chosen to use FreeRadius as our AAA server, but are experiencing
some problems.

As far as I can tell, everything is fine till I get the "[eap] NAK asked
for unsupported type 21" error?

Could anyone give me any pointer or ideas about what I am doing wrong,
and how I can fix it?

Sincerely,
Kristoffer Milligan
