WIMAX problem

[Dimitris Theofilatos]

Hi,
I am using freeradius 2.1.3 and i try to enable Wimax support.
I built the wimax module and i placed it at the post-auth section of 
sites-enabled/default file.
I use EAP-TTLS with mschap2.
At the Access-Accept packet from Freeradius to the ASN-GW i use i can't 
see any WIMAX VSA's.
There are only MS-PPE keys.
Also at the log of radiusd i get the next log for wimax module

[wimax] MIP-RK = 
0xf65a926b20cd57553c06a7a4880bf8aa08eaf40a6426edb4653d4d5e8f7eed3ff9ad4b9fedf9c30d0ea99fef7ae9bfe60afcbe73e56cf41b43d74427ce7f7196
[wimax] MIP-SPI = 6f74f1eb
[wimax] WARNING: WiMAX-MN-NAI was not found in the request or in the reply.
[wimax] WARNING: We cannot calculate MN-HA keys.
[wimax] WARNING: WiMAX-IP-Technology not found in reply.
[wimax] WARNING: Not calculating MN-HA keys

Do i have to configure something else?
