I do all steps, only change my IP. My local ip is 172.16.0.2, and my
/etc/hosts is:

> 127.0.0.1       localhost localhost.localdomain
>
> 172.16.0.2      DC1.samdom.example.com DC1

>
> ff02::1 ip6-allnodes
>
> ff02::2 ip6-allrouters

> my /etc/resolv.conf is:

> root at SAMBA:/usr/local/samba/bin# cat /etc/resolv.conf

> search samdom.example.com

--server-role=dc --use-rfc2307 --dns-backend=SAMBA_INTERNAL --realm=
SAMDOM.EXAMPLE.COM --domain=SAMDOM --adminpass=Passw0rd
