[Samba] Samba AD with advance password policies

[Krutskikh Ivan]

Hi everyone,

I need an active directory instance with some non-standart policies to
users passwords:

1) Group users minimal length is 6, Group Administrators 12
2) Should have special symbols (!#$) and numbers are required
3) Password must not be dictionary words or based on them ( no admin, user,
sysop etc)
4) Each new password must differ to the old one by 50%.

Can I do all those in samba ad?

The thing bothering me is 1 and 3.

Thanks in advance!
