Please send a debug log from wpa_supplicant showing this.

I'm not aware of any bug in wpa_supplicant or madwifi driver that would
cause this. There are known issues with number of RADIUS servers not
following EAP specification, though, and 0.4.x versions of
wpa_supplicant may include more EAP workarounds that would allow it to
ignore such incorrect behavior.

I cannot answer this before seeing the debug log.. I would recommend
testing with the latest devel branch (0.4.x release or snapshot) if you
want to easily verify whether a workaround for the issue you are seeing
has been added.
