samba - Dec 2011 - linux smbclient NT_STATUS_LOGON_FAILURE, mount.cifs works

From linux, I can mount.cifs, but smbclient fails:
Searching through the archives, I found: "IIRC you should use mount.cifs 
instead of smbclient on an ADS"
But for my application, it would be *really nice* to be able to use 
smbclient, but if I have to, I can setup an
intermediate server that can run mount.cifs (the main application server 
is locked into an old kernel version
that doesn't support mount.cifs... ).

Any suggestions are appreciated.

Thanks,
E.
