Azure MFA Authentication with Radius / NPS Plugin

Hi guys,

i followed the cookbook 

https://docs.fortinet.com/document/fortigate/6.2.0/azure-cookbook/517582/configuring-forticlient-vpn-with-multifactor-authentication

And the authentciation works, if i disable with the NPS Plugin. However with the plugin active it does not work, it says connection fails. The connection test itself works, always. This logic does make sense when i read how the radius server act with an active Azure Plugin. But because there is a cookbook, i expect that this special behaviour is taken care of, which seems it isnt.

Can anyone point me further, im a fortinet newbie.

Kind Regards
