I Was thinking perhaps client not setting either NTLMSSP_TARGET_TYPE_SERVER or NTLMSSP_TARGET_TYPE_DOMAIN or NTLMSSP_TARGET_TYPE_SHARE (the one that server sets in type 2/challenge message) in type 3 message is a problem but it is not (as per page 33 in ms-nlmp document). cifs client should change to code Target Name instead of NetBIOS domain name from Target Info to calculate ntlmv2 response but that is not the problem here (because they happen to be the exact same). Is there a way to check what kind of response this SMB server expects i.e. NTLMv1 or NTLMv2? There may be a conf file on the server effecting that. Also, if you can provide wireshark trace for any other client besides cifs client successfully authenticating with this server, that would be useful too.
