[Samba] Password problems with Samba-3.0.4

I'm apparently not the first person to have this problem, but I can't
find a fix for it anywhere on the web, or in Usenet.

Here's the scenario:
I upgraded from 2.2.8a to 3.0.4 during a recent hardware move.

All of my client machines are connecting properly, but my users can't
change passwords from their WinXP clients now. (Client error message
"bad username or incorrect old password".)

This happens with any user account, including newly created test

Here is what I get in the log.%MACHINENAME% file:
  decode_pw_buffer: incorrect password length (12889175).
  decode_pw_buffer: check that 'encrypt passwords = yes'
(other versions of this error give lengths of (1000352699) and

I already have 'encrypt passwords = yes' in my smb.conf file, and
applied all the patches to the client machine, as well as the
"require_sign_or_seal" registry hack.

I've manually set the password from the console, and I can login
that password, so it's definitely not something as simple as the new
password being thrown out by PAM.

If this weren't a binary install from the latest samba.org RPM file,
suspect that one of the executables or libraries were corrupted.  Any
help would be appreciated.
