Oh, wait, sending everything in Unicode works. Smbclient sends Unicode.
The problem with jCIFS is the Unicode password isn't aligned properly.
Oops. It's interesting that the plaintext password in ASCII with
everything else Unicode actually worked.

Ethereal doesn't quite decode it properly though. I think it's expecting
the ANSI Password Length to be 1 with a 0x00 byte in plaintext mode. I
seem to recall seeing that.
