[Samba] How to Change samba's PW from XP

[jayb]

Unfortuntely, the Samba LDAP is separate from our LDAP Authentication server.
So, when the user changes his Windows password, it changes the Authentication server just fine.

Then when the user accesses his Samba file server he gets prompted for
Username / password where he has to enter in an old password until someone changes
it to the new password on the samba server.

If only there was some way for the XP box to tell the 
samba server to put up a "password change" dialog box. Or the push
A password change to the samba server from within windows.

Thanks
jay

You should be able to change the password as per normal Windows usage if 
Samba is using the LDAP server.

Password setting seems to be a two-step process. Firstly, Samba updates 
its password then it uses a script to run the local passwd program to 
change the local Linux/Unix password. If either fails, the password is 
not updated (as far as I can tell).

Samba uses "expect" to test the prompts from passwd to feed it the 
password and confirm completion.
I ran into a problem with this when my smb.conf password script didn't 
match what my passwd program was sending out, preventing me from 
changing password from Windows. :)
