NPS Extension for Azure MFA: IP_WHITE_LIST_WARNING::IP Whitelist is being ignored as source IP is missing in RADIUS request in NasIpAddress attribute. RRS feed

  • Question

  • Hi,

    After installing Azure MFA extension on our NPS server and registering with our tenant we started seeing Errors (event ID 4)  from Microsoft-AzureMfa-AuthZ/AuthZAdminCh for the client IPs what were white listed in the registry per KB

    It looks like one of our RADIUS clients (access point) is not sending ratNASIPAddress attribute in the request. 

    Is ratNASIPAddress something we need to configure in NPS or should be done on the client itself?
