I am experimenting with using AD for 802.1x as an authentication option as it would allow me to get away from using Windows NPS as Radius. I have successfully configured the AAA Server and SSID and can authenticate both Windows and Android devices, however iPad 12.0 iOS (I do not have any other devices to test with, so problem could be limited to this or, possibly, unlimited) appear to successfully authenticate (receive no errors at AD or in ZoneDirector troubleshooter) but a message displays that the device was unable to join. I, initially, thought it may have something to do with MFP settings, however, changing those did not appear to fix the issue, nor did switching between strict AES or Auto (TKIP+AES) help.
