Hello Chaps,
Yesterday we disabled NTLM 1 at the Domain level and we noticed this morning the Azure MFA plugin installed on NPS server stopped working. Tried uninstalling the plugin and install the latest version from Microsoft but that didn't help. The error message on NPS logs was "An NPS extension dynamic link library (DLL) that is installed on the NPS server rejected the connection request". We had to re-enable NTLM v1 to get the MFA working. Is there a way to force the plugin to use NTLM v2 or Kerberos for authentication? Operating system is Windows 2012 R2.
Thanks,
Kiran

Validar que el registro HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\AzureMfa exista la variable OVERRIDE_NUMBER_MATCHING_WITH_OTP = FALSE
SI esta no se encuentra se debe crear tipo string:
regedit HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\AzureMfa
OVERRIDE_NUMBER_MATCHING_WITH_OTP = FALSE
Solucionadoooo.....
