Hi,
I've had this problem on FreeBSD. Basically the behaviour of 'passwd'
changed somewhere between releases 5 and 7. I solved this by writing a
shell wrapper for the passwd tool. As simple as:
#!/bin/sh
/usr/bin/passwd -l $1
echo "Password Changed"
Call the file "smbpass.sh" and alter smb.conf accordingly:
passwd program = /root/smbpass.sh %u
passwd chat = *Password* %n\n *Password* %n\n *Changed*
unix password sync = Yes
Using wrappers makes a great deal of sense...
For a mission critical production system you may want to put more error
checking into the shell script, but hey, you get the idea ;-)
Hope this helps.

I can't get my Samba PDC (FreeBSD 7,0-BETA3) changing UNIX passwords

I now have the password chat debug active and I have loglevel 100.
I am not certain about the syntax in the password chat. But if I from
a console try to change the password of a given user (here testuser1),
I see these lines:
mflserver3# /usr/bin/passwd testuser1
Changing local password for testuser1
New Password: (entering the password)
Retype New Password: (entering it again)
From that i guess the expression in the chat would be:
*Changing*local*password*for* %u\n *New*Password* %n\n
*Retype*New*Password* %n\n

As told, I'm not confident with the syntax. Have I made it wrong? Or
can you see anything else from the log that can pinpoint the problem?
I would believe that there must be several admins out there who use
the combination of of Samba and FreeBSD without having these problems.
