samba - Aug 2009 - Password Sync not letting users to change password.

Dear all,

Ubuntu 8.04 Server
Samba 3.0.28a configured as PDC.

I want to give options to samba users to change their own passwords and sync
it with the unix passwords whenever they change it.

I have used the following in my smb.conf file

unix password sync = yes
passwd program = /usr/bin/passwd %u
passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:*
%n\
n *password\supdated\ssuccessfully* .

I get an option to change the password in winXP but, after entering the new
password, the server returns "You don't have permissions to change your
password"

can anybody help me

Go to a Linux command prompt and try to change a password. Compare the 
password change dialogue with the passwd chat line in your smb.conf 
file. On my Debian/Lenny server, the chat line is:
       passwd chat = *Enter\snew\sUNIX\spassword:* %n\n 
*Retype\snew\sUNIX\spassword:* %n\n 
*passwd:\spassword\supdated\ssuccessfully*

The chat line you have should work, but you never know.

Also, check in the user manager (both the Linux and Windows ones) to 
ensure that users are actually allowed to change their passwords. It may 
be that they have accidentally been denied that right.
