Windows mobile unable to authenticate [FreeRadius+Active directory]

[Burn Zero]

Hi,

FreeRadius version 3.0.13

We are using FreeRadius+Active directory setup in our environment to
authenticate users for the WIFI. The clients are authenticated using
server side cert + their Active directory credentials. This is working
properly except windows phone users.

Users who own windows phone are unable to authenticate via Freeradius.
Below is the debug error log when they try to connect WIFI.
