Smb.conf (domain names made 'generic'):

# Global parameters
[global]
        dns forwarder = 4.2.2.2
        netbios name = MACHINE254
        realm = INTERNAL.COMPANY.COM
        server role = active directory domain controller
        workgroup = INTERNAL
        idmap_ldb:use rfc2307 = yes

[netlogon]
        path = /var/lib/samba/sysvol/internal.company.com/scripts
        read only = No

[sysvol]
        path = /var/lib/samba/sysvol
        read only = No

[Test-Share]
        path = /home/test-share
        writable = yes
        create mode = 0770
        directory mode = 0770
        guest ok = no

Windows reported that the machine joined the domain
when I used the windows interface at System
Properties -> Computer Name.
