Kiran,
The WiMAX forum does not define the user authentication between HA and
HAAA. HAAA solely depends on the shared secret between HA and HAAA to
validate the request from HA is good. Its security models uses the MIP
keys to authenticate users has been authenticated into ASN gateway at
HA. What you need to do is to set AUTH-TYPE := Accept if it is HA. You
may uses hints to indicate it is HA instead of ASN gateway.
Thanks,
Jay Xiong
