samba - Jul 2006 - Password change for win clients

Hi,

I'm using Samba 3.0.7 on Linux Rad Hat 3 update 4

I'm trying to change passwords over windows (STRG+ALT+DEL)
But it doesn't work.

Is this the right way?

Server role: ROLE_STANDALONE

No PDC!!!

smb.conf parameters:

        passdb backend = tdbsam
        passwd program = /usr/bin/passwd %u
        passwd chat = *old*password* %n\n *new*password* %n\n
*new*password* %n\n *changed*
        pam password change = Yes
        unix password sync = Yes
