[Samba] Secondary for samba zone

[Robert Moskowitz]

Most is all there, right.  But with BInd 9.9 there is a 'new' option 
that I needed on my DNS server.

On the Samba AD, I see:

dig home.htt SOA

; <<>> DiG 9.9.4-RedHat-9.9.4-18.el7 <<>> home.htt SOA
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 38095
;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 1, ADDITIONAL: 2

;; OPT PSEUDOSECTION:
; EDNS: version: 0, flags:; udp: 4096
;; QUESTION SECTION:
;home.htt.            IN    SOA

;; ANSWER SECTION:
home.htt.        3600    IN    SOA    homebase.home.htt. 
hostmaster.home.htt. 4 900 600 86400 3600

I don't like the email default, but then shouldn't be getting emails to 
it.  But the timers are right.

But over on the main DNS server that will secondary this domain, there 
is a change to the zone description:

     zone "home.htt" {
         type slave;
         file "slaves/bak.home.htt";
         masterfile-format text;
         masters {192.168.192.2; };
     };

Note the new "masterfile-format text" line.  This is if you want a nice 
text file for the slave zone to read, rather than the more efficient 
binary file.  And here is what is in that file right now:

# more slaves/bak.home.htt

BTW, this is probably the simplest way to get a dump of your samba dns zone!

Now to set up all the other secondaried zones!

I am wondering if the dyndns updates are incrementing the serial 
number.  More tests to figure that out.
