&
Intune: 802.1x Wi-Fi, NPS and user PKCS certificates | Katy's Tech Blog (katystech.blog)

Great posts and i got it to work in my testlab.

Now when i try to get this to work in a production environment i ran in to some issues.
i have tried for quite a while to do some troubleshooting but it always ends up in a dead end.

 

The error i get in the NPS eventlog is:

Network Policy Server denied access to a user.
Contact the Network Policy Server administrator for more information.

In the testlab everything is fine:

I have added in the Constraints/Authentication Methods/EAP Types: Microsoft Protected EAP (PEAP) on the NPS server just to see if something is wrong with the NPS but it works to authenticate with username and password
So there is something with the certificate but i have double and triple checked everything.

Any ideas are welcome

 
Best Regards

Tobias
