Hi, Thanks for your post. MAC address authorization is performed when the user does not type in any user name or password, and refuses to use any valid authentication method. In this case, Network Policy Server (NPS) receives the Calling-Station-ID attribute, and no user name and password. To support MAC address authorization, Active Directory Domain Services (AD DS) must have user accounts that contain MAC addresses as user names. For more detailed information about MAC Address Authorization, please refer to the below article. Hope it helps.
