Issues with RD Gateway and MFA RRS feed

  • Question

  • Hi All,


    I am trying to configure multifactor authentication with Azure MFA on my remote desktop gateway. I followed this article:

    https://docs.microsoft.com/en-us/azure/active-directory/authentication/howto-mfa-nps-extension-rdg

    All seems ok but it is not working as expected. When I try to access a remote desktop I get the notification on my phone. When I approve, the remote desktop keeps trying to connect and I get the notification on my phone 2 more times. Eventually the RDP just times out.


    On my NPS server with the NPS extension I can see in the eventlog that access has been granted. On my remote desktop gateway in the NPS logs I can see this:

    The RADIUS Proxy received a response from server X.X.X.X with an invalid authenticator.

    Where X.X.X.X is my NPS server.

    All servers are windows server 2019. My testuser has an Azure AD Premium P1 license (and an office365 business premium).

    Any ideas on what could be wrong with my setup?
