[Samba] password sync unix

[Gary Dale]

What you haven't explained is what happens when the users try to change 
their passwords from Windows? In fact, your explanation suggests you may 
have things backwards.

The Unix password sync is just that. It synchronizes the Unix password 
with the Windows (samba) password. When the user changes their Windows 
password, it updates the Unix password in /etc/password (or shadow). The 
Windows password is stored in the samba database.

Your smb.conf looks like you aren't handling Windows logins locally. 
What I'd suggest doing is using the SWAT wizard to make your server a 
member server in your Windows domain. That should create a new smb.conf 
appropriate for that role.
