Now for the next question. I think (hope?) that I am quite close now.

In order to add a machine to the domain, I think that I need to add a record to 
samba's DNS table. But samba_dnsupdate isn't working:
# samba_dnsupdate -d 5

As you can see updates are not allowed. But my smb.conf looks like this:
[global]
          workgroup = MYAD
          realm = MYAD.my.domain
          netbios name = SAMBA4
          server role = active directory domain controller
          idmap_ldb:use rfc2307 = yes
          #       log file = /var/log/samba/samba.log.%m
          log level = 3
          allow dns updates = True
          dns forwarder = 192.168.99.2
