I'm running with 'security = server' and everything was working fine with version 3.0.24 of samba. I upgraded to version 3.0.25 and I could no longer access my shares. My XP client now reports, "The system cannot find the device specified." and a client->server network capture shows a logon failure: 10.1.2.4 10.1.1.83 SMB Negotiate Protocol Request 10.1.1.83 10.1.2.4 SMB Negotiate Protocol Response 10.1.2.4 10.1.1.83 SMB Session Setup Andx Request, NTLMSSP_NEGOTIATE 10.1.1.83 10.1.2.4 SMB Session Setup Andx Response, NTLMSSP_CHALLENGE, Error: STATUS_MORE_PROCESSING_REQUIRED 10.1.2.4 10.1.1.83 SMB Session Setup Andx Request, NTLMSSP_AUTH, User: DOMAIN\user 10.1.1.83 10.1.2.4 SMB Session Setup Andx Response, Error: STATUS_LOGON_FAILURE A server->domain controller network capture shows the following repeating sequence (note that the anonymous Session Setup is successful): 10.1.1.83 10.1.1.1 TCP 45010 > microsoft-ds [SYN] 10.1.1.1 10.1.1.83 TCP microsoft-ds > 45010 [SYN, ACK] 10.1.1.83 10.1.1.1 TCP 45010 > microsoft-ds [ACK] 10.1.1.83 10.1.1.1 SMB Negotiate Protocol Request 10.1.1.1 10.1.1.83 SMB Negotiate Protocol Response 10.1.1.83 10.1.1.1 SMB Session Setup Andx Request, User: anonymous 10.1.1.1 10.1.1.83 SMB Session Setup Andx Response 10.1.1.83 10.1.1.1 TCP 45010 > microsoft-ds [FIN, ACK] 10.1.1.1 10.1.1.83 TCP microsoft-ds > 45010 [FIN, ACK] 10.1.1.83 10.1.1.1 TCP 45010 > microsoft-ds [ACK] Downgrade back to version 3.0.24 and the problem goes away.
We think we fixed this with 3.0.25a. Please re-open this bug if 3.0.25a is still a problem. Volker
