I don't think samba is involved in the DNS updates for clients.
(Other than for handing out Kerberos tickets).

Your /usr/local/samba/private/named.conf.update should contain
something like this:

/* this file is auto-generated - do not edit */
update-policy {
        grant YOUR.REALM ms-self * A AAAA;
        grant administrator at YOUR.REALM wildcard * A AAAA SRV CNAME TXT;
        grant YOURSERVER$@YOUR.REALM wildcard * A AAAA SRV CNAME;
};

I think the first grant line is supposed to allow your clients to
update their own A or AAAA records.

I have CCed samba-technical in case someone there can confirm this.
