I set up a Samba server on RHEL 5.4 using 3.6.0pre1 with "max protocol = SMB2". The authentication process always fail when I try to use a Win7 client (7100RC) to access a share.

Log shows smbd panic occurred and core dump points to line 643 in source3/smbd/smb2_sesssetup.c:

    643:	if (session->server_info->guest) {

It can be verified that session->server_info is a NULL pointer.

It seems that setup_ntlmssp_server_info() in smbd_smb2_spnego_auth() was not executed:

    788:	if (!NT_STATUS_IS_OK(status) &&
    789:			!NT_STATUS_EQUAL(status, NT_STATUS_MORE_PROCESSING_REQUIRED)) {
    790:		status = setup_ntlmssp_server_info(session, status);
    791:	}

When I comment out line 788, 789 and 791, Win7 can access the share.

Please take a look. Log, core dump and pcap will be attatched.

Thanks,
zn
