samba - Apr 2015 - Sernet packages necessary to create an AD and a Client servers

Hi, maybe I'm starting to be annoying with my noob questions (i'm
sorry),
but i've another questions: What packages from SerNet I've to install to
make an AD server?, and a client server with winbind?.
I've tried to create an AD server with:

apt-get install krb5-user ntp acl sernet-samba-ad attr
samba-tool domain provision --use-rfc2307 --realm=somewhere.red
--domain=SOMEWHERE --adminpass="Passwd12" --server-role=dc
--dns-backend=SAMBA_INTERNAL
/etc/init.d/sernet-samba-ad restart

and I can create a domain, but when I run "smbclient -L localhost -U%"
fails.
smb.conf is right (just like a working samba 4.1 server) and samba daemons
are running, then I think I'm missing something.

Thanks!!
