Hi experts, I'm getting really frustrated on this... I had the server rebuilt with REHL 5 and FreeRadius2.1.7. It was running REHL 4 with FreeRadius2.1.6. It looks like the server will send the last "challenge" and the client won't reply anymore... The ntlm_auth part should be working right because when I do "radtest 'gtcorp\\dzhao' <password> localhost 0 test123" it works fine... Sending Access-Request of id 119 to 127.0.0.1 port 1812 User-Name = "gtcorp\\dzhao" User-Password = "<password>" NAS-IP-Address = 10.26.105.105 NAS-Port = 0 rad_recv: Access-Accept packet from host 127.0.0.1 port 1812, id=119, length=41 Tunnel-Type:0 = VLAN Tunnel-Medium-Type:0 = IEEE-802 Tunnel-Private-Group-Id:0 = "3" Tunnel-Preference:0 = 0 However it's not working when I have a laptop plugged in doing PEAP/802.1x with the same user account... The debug output is attached. Please help!! Thanks!!! Difan Zhao, M.Eng Network Engineer Guest-Tek Interactive Entertainment Inc.
