802.1X Authentication NPS Reason Code 293

I want to allow my Cisco telephones 802.1X access via EAP-TLS using MIC Certificates.

If configured it similar as MikeLascha stated in his post:
https://social.technet.microsoft.com/Forums/en-US/6d78c698-a087-48cb-bc73-9566aa61bf10/using-nps-with-cisco-ip-phones?forum=winserverNAP

But I get the Reason Code 293:
The certificate is not valid for the requested usage.

How can I solve this problem?

Hi,

We need to trace network monitor to find some clues. However, analysis of network traffic is beyond our forum support level and due to forum security policy, we have no such channel to collect user log information. So, we recommend you open a case with MS Professional tech support service, they will help you open a phone or email case to Microsoft, so that you would get a technical support on a one-to-one basis while ensuring private information.

Here is the link:
