Hi,
I have recently implemented NPS server for wireless authentication and it is working fine. I wanted to have more security whoever trying to connect the wireless network to our organization. I want to implement mac filtering with AD user authentication (currently user authentication is enabled). I gone though the below article and it didn't helped for me.
Enhance your 802.1x deployment security with MAC filtering

In the article, they have mentioned to add device mac address in Calling Station ID (in dial in tab), where I couldn't able to find the option in the dial in tab.
The only option is available is below (screenshot below). I have tried to enable verify caller-ID and entered the device mac address, but still the other devices are able to connect from the same user account.
