We integrated NPS extension with Palo Alto VPN, we able to authenticate VPN using MFA. However, we get two time verification call, SMS, OTP and App verification to connect to the VPN.
There is 30 seconds lag between 1st and 2nd MFA Authentication.
Time out value is set to 60 sec on Palo Alto and 1 retry only, still experiencing the same issue.
In NPS, we are getting error below:
**Reason Code: 9 Reason: The request was discarded by a third-party extension DLL file.**
NPS Extension for Azure MFA: NPS Extension for Azure MFA only performs Secondary Auth for Radius requests in AccessAccept State. Request received for User with response state AccessReject, ignoring request.
I have tried all the suggestions on Internet but no luck.
Did anyone experience this issue or any suggestion?
