Problem changing password from windows client

[Ian Moore]

Hi, I use samba on a FreeBSD server with a mixture of win95 & win98
clients with encrypted passwords disabled.
My problem is I can't change user's passwords from the windows clients.
Sorry if this question has been answered already, but I have spent ages
searching thru the mailing list archives without finding a solution.
Has anybody actually got this to work?
I am also a little confused about wether the smbpasswd file is used when
you don't have encrypted passwords.
When I first tried to change passwords, I got errors in the smb logs
about the oem_password being NULL.
So then I used swat to set a password in smbpasswd for a user. Now when
I try to change that user's password from the windows client I get:

[2001/04/22 16:21:23, 0] smbd/chgpasswd.c:check_oem_password(693)
  check_oem_password: incorrect password length (-1125595242).
in the smb log file and Windows says the old password is incorrect.

I assume oem_password is the password in the smbpasswd file?
If so, I suspect it's not even getting to the point of running the
passwd program to change the unix password. It looks to me like it
checks the old password with the one stored in smbpasswd and it's not
the same, so it tells the client to return an error and ask for the old
password again.
Or is it just that my passwd chat line is wrong?
I have tried both with & without the Unix Password Sync setting, but
neither seems to fix the problem.

My smb.conf file looks like this:
# Samba config file created using SWAT
# from localhost.threed.com.au (127.0.0.1)
# Date: 2001/04/22 14:51:35

Any help would be appreciated,
