  • Hi Steven,

    Thank you for the answer.

    I know how to develop NPS extensions - I have been doing that for many years now. My question is how MS-CHAPv2 request is translated to NTLMv2 authentication request by NPS. It is possible with the flag enabled (in the link I posted)

    Best regards,
