[Samba] check password script for samba 4 ad dc

[Krutskikh Ivan]

Hmm, looks like it's not. I've just set the password for something that
cracklib-check would argue using both ad management tools and at windows
login. Should it work that way or I'm missing something?

 My dc's smb.conf:

[global]
        workgroup = KURSK
        realm = KURSK.MTT
        netbios name = DEBIAN-DC
        server role = active directory domain controller
        server services = s3fs, rpc, nbt, wrepl, ldap, cldap, kdc, drepl,
winbindd, ntp_signd, kcc, dnsupdate
        idmap_ldb:use rfc2307 = yes
        check password script = /usr/sbin/cracklib-check
        log level = 4

[netlogon]
        path = /usr/local/samba/var/locks/sysvol/kursk.mtt/scripts
        read only = No

[sysvol]
        path = /usr/local/samba/var/locks/sysvol
        read only = No
