No - the account I am testing with is unique to the CIFS server.

The account I am using is only in the "test" domain on the server.  The
account was setup specifically for me to test with, so I'm fairly certain
its the only account with that name on that server.

The client's concern (I'm developing an FS for the client) is that since
the Mac users *can* login without a domain, then they *will* and then run
into these issues.  I am not sure why SMB is allowing it.  I've tried
passing in various "default" domains to JCIFS (".", "$HOSTNAME", "NONE"),
but nothing seems to work but the actual domain name.  I should also note
that we are using NTLM authentication, but that doesn't seem to make a
difference - specifying the credentials inline with the URL has the same
effect sans domain name.

The client says "Yes, we are using NAS as the source share and it's SMB
protocol stack could well be old."

Thanks for any other insight you can provide.
