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.
