There is an interesting fact, if you add:

    dedicated keytab file = /etc/krb5.keytab
    kerberos method = secrets and keytab

to smb.conf and then join the domain with:

net ads join -U Administrator (or another user capable of joining
machines)

You will get the computers account created in AD and the keytab
created, so why do you feel the need to precreate the machines in AD
and use an extra package to join the domain ?
