List, This is the first time i configure the free radius to integrate with AD on window 2k3. After i finished installing and setting up free radius i can authenticate for user domain. But on workstation that was joined into domain i can't auth for this user. On the screen shot when i run command radiusd -X for debugging radius showed: no EAP message, not doing EAP. I used ntlm_auth with samba for authentication user daomain. How can i fix this problem? I attached my configuration on free radius in the attach file. Thanks, Sang Le
