[Samba] password strenght doubt

[Guido Lorenzutti]

Hi people! I have a few problems with the password strength in Samba.
I have a PDC with LDAP on Debian Stable, with a few packages from backports.
The problem is that I can't find a way to enforce strenght to the 
passwords of the users. I can't define a policy to force things like: 
number of uppercase letters, number of downcase letters, number of 
numbers in the password, to check the diference between the new and the 
old, to store a list of old passwords to check... I mean, things that 
are requiered to enforce some policy of security by my company.
Bottom line? The users can put his username for password! Not even that 
is checked...

It's something wrong in my setup or is a feature request? I see min 
password length.. but.. the rest?
