[Samba] password strenght doubt

[Gary Dale]

I think you'll find at least some of these are Windows Policies and 
would not be reflected in the smb.conf file. If you check the Samba 
Howto collection and the Samba by example documents at samba.org, you'll 
find examples of how to set some of the policies.

To be honest, I've never gone beyond requiring password changes, minimum 
lengths and histories.  :)
