[Samba] FW: Password change on Windows 2000 clients not working

Hi, I sent this in a couple of days ago and have only gotten one
suggestion.  Can someone read the below problem and try to help me out?
I have searched everywhere for a solution to this and have tried
numerous 'passwd chat' strings to no avail.

Help is much appreciated!

Subject: Password change on Windows 2000 clients not working

Hello, I have searched hi and lo for a solution to being unable to
change passwords from Windows 2000.  Everything seems to work fine,
shares, etc.  but when I press ctrl-alt-del to bring up the Change
Password dialogue, I get the message that "The user doesn't exist or
the
password was entered incorrectly" from Windows.  

I am running Samba 2.2.3a on Mandrake Linux 8.2

In my logs, I see the following at the computer I was testing on:

[2002/08/08 18:47:17, 0] smbd/chgpasswd.c:chgpasswd(474)
  Password Change: user sralph, New password is shorter than minimum
password length = 5
[2002/08/08 18:47:19, 0] smbd/chgpasswd.c:chgpasswd(474)
  Password Change: user sralph, New password is shorter than minimum
password length = 5

  check_oem_password: incorrect password length (-1576411277).

This is using the commented out "passwd chat" line.  Using the
original
"passwd chat" line that is listed below, these errors were logged:

[2002/07/22 17:03:24, 0] smbd/chgpasswd.c:chgpasswd(541)

Here is my smb.conf file [global] section

#Samba Configuration file

  workgroup = pjglease.com
  netbios name = serve-on
  server string = Workgroup Server

  security = user

  passwd chat debug = true

'Machine Account' -s /bin/false -M %u

  #Logs
  log file = /var/log/samba/log.%m
  max log size = 50

  #Optimizations
  socket options = SO_RCVBUF=8192
  socket options = SO_SNDBUF=8192
  socket options = TCP_NODELAY

  #naming

  #Home Dirs
  logon drive = Z:
  logon home = \\serve-on\%u

  #printing
  #printcap name = lpstat
  #load printers = yes
  #printing = cups

Hope someone out there can make sense of this email and what's going on
... and if you can, that would be fantastic!

OK, lets take a look.

This is after attempting a password change I assume?

You may be interested in samba-2.2.5 (with or without LDAP support) 
compiled for Mandrake 8.0, 8.1 and 8.2, available from ftp.samba.org, 
http://ranger.dnsalias.com/mandrake/samba or 
http://people.mandrakesoft.com/~staburet/samba

Looks like your password is too short for your cracklib options (set in 
/etc/pam.d/passwd

Anyway, are you sure you need to have samba change the unix password? We 
haven't until recently when we switched to LDAP since some app can auth 
against unix passwords but not against pam. In most cases, pam_smb works 
very well.

Also, you may want to investigate using "pam password change = yes".

The original one should work. If you are unsure, run your 'passwd 
program' on the command line and see.

Looks like you had changed 'passwd program' also, according to this.

Are you sure you typed the right password?

Once again, you need to use a longer password, or change the cracklib 
settings.

I don't know if I did, but let's hope we can get it fixed.

Please retest using Samba 2.2.5.  This looks like a known bug.
