802.1x using Active Directory as Freeradius's Backed

Hi All, My company will implement WPA2-Enterprise as wireless user authentication method. We already use Active Directory so we want use that AD as authentication service for freeradius too. I already config the freeradius based on these link : http://wiki.freeradius.org/guide/FreeRADIUS-Active-Directory-Integration-HOW... this link http://deployingradius.com/documents/configuration/active_directory.html https://www.eduroam.us/node/44 but no good so far, we always failed to authenticate users. Attached debug output. Regards Andi Mappesona
