[Samba] smbclient against win7 server cifs/smb2

[Shirish Pargaonkar]

When lmcompatiblity level is set to 5, against a window7 server,
source3/smbclient fails to
authenticate with error NT_STATUS_LOGON_FAILURE using cifs

        server signing = enabled
        client signing = enabled
        client ntlmv2 auth = yes

Am I missing something in either smb.conf setup or Windows7 settings
for it to fail for me?

And not sure whether source3/smbclient works with smb2 (tcpdump does
not capture anything)

        server signing = enabled
        client signing = enabled
        client ntlmv2 auth = yes
        max protocol = smb2
        min protocol = smb2

Again, I may have incorrect setup!

When I can compile source4/smbclient, will attempt above with that client.
