[Samba] Samba 3.5.6 Syncing passwords

I used to run NIS.    I did not use the "pam password change" option-  the
"unix password sync" "password program" and "password chat" options were

If you run smbpasswd from command line as a regular user, what happens?  All
I can guess is that samba things the unix script failed for some reason.
Can you create a more complex pw change script to capture the user name and
password to a log file?  Were the passwords already in sync?

The passwd command should be running as root, so you should not need to have
the old password.  Did you try "passwd -r nis" instead?  

How about if the user has a /etc/passwd unix acct and not nis?

Subject: [Samba] Samba 3.5.6 Syncing passwords


I'm running a Samba 3.5.6 standalone server on FreeBSD 8.1, with XP and 7 
clients. I can't get Samba to syncronize Windows & NIS passwords, in fact 
it's behaving strangely from what i think:

Relevant (i think) parts of smb.conf:

encrypt passwords = yes
passdb backend = tdbsam
pam password change = yes
unix password sync = yes
passwd program = /usr/bin/passwd '%u'
passwd chat = *New*password* %n\n *ReType*new*password* %n\n 

When 'pam password change' is set to 'yes' a user can change his windows 
password, if not the UNIX NIS password is changed, but not the Windows one, 
and it says the user can't change it...

I have not made any modifications to my pam configuration, so... any clue?
it posible to sync passwords or just one of them can be changed by the user 
from Windows?
