[Samba] Can't change password with Windows XP (Change password feature)

[James Marcinek]

Hello Everyone,

I've been trying to figure out why I can't change passwords with my windows
clients. I thought that at when I first built my smb.conf I could.

I'm running RHEL3 (I also have another system at a different location running
FC3 with the same problem ).

I've been looking through my smb.conf (see excerpts):

# You may wish to use password encryption. Please read
# ENCRYPTION.txt, Win95.txt and WinNT.txt in the Samba documentation.
# Do not enable this option unless you have read those documents
  encrypt passwords = yes
;  smb passwd file = /etc/samba/smbpasswd
        passdb backend = tdbsam
 
# The following are needed to allow password changing from Windows to
# update the Linux system password also.
# NOTE: Use these with 'encrypt passwords' and 'smb passwd file' above.
# NOTE2: You do NOT need these to allow workstations to change only
#        the encrypted SMB passwords. They allow the Unix password
#        to be kept in sync with the SMB password.
        unix password sync = Yes
        passwd program = /usr/bin/passwd %u
        passwd chat = *New*UNIX*password* %n\n *ReType*new*UNIX*password* %n\n
*passwd:*all*authentication*tokens*updated*successfully*

We get an error now that states not authorized (or something like that) to
change password. These are Windows XP Pro systems. 

The version of Samba is:

samba-3.0.9-1

This is driving me crazy.

Can anyone help me out?

Thanks,

James
