[Samba-it] Criteri password samba pdc

[Info Bcl]

Ho finito di configurare samba come pdc (uso la ver. 3.0.6), ma facendo
alcune prove sulle password di accesso ho notato che non vengono considerati
i criteri impostati con pam riguardo la complessità delle password. 
Inoltre consente di reinserire le password precedentemente utilizzata, cosa
che vorrei impedire per adeguarmi alla legge sulla privacy.
Sapete darmi qualche indicazione su cosa devo modificare per usare le
restrizioni dell'accoppiata passwd + pam?

Questo è il smb.conf che utilizzo:

# Samba config file created using SWAT
# from 127.0.0.1 (127.0.0.1)
# Date: 2004/08/28 10:36:34

# Global parameters
