[Samba] Password Sync

[Listas do Fernando]

Hi palls

How can I syncronize LINUX and SAMBA passwords?
I've tried to configure my smb.conf like this:

[global]
    encrypt passwords = no
    smb passwrd file = /usr/local/private/smbpasswd
    unix password file sync = yes
    passwd program - changepass %u

But doesn't works.
When I type: # passwd user
The programa only change the linux local password.

Thanks.
