That link contains instructions to use Active Directory to authentiate login to the on-premises version of cnMaestro using Windows AD. Is that what you're trying to do? Or are you trying to use AD to authenticate users connecting to a WPA2 enterprise wireless LAN?
If it is the latter, those instructions are not applicable. Instead, you need to run a RADIUS server on your windows AD server e.g. by installing and running Windows Network Policy Server. Once you have done that you can then set the authentication mode for the WLAN on the cnPilot AP to WPA2-Enterprise (instead of open or WPA-PSK) and configure the RADIUS server IP and secret on it. The users can then connect to Wi-Fi using their AD username and password.
