I have been working on this too, and found that I needed to add the

samba-tool dns add dnsserver mydomain.org <http://mydomain.org>
newname CNAME realname
...and I use the Windows DNS tool to look at the record in the
mydomain.org <http://mydomain.org> zone, it maps "newname" to
"realname." <--- NOTICE the "dot" at the end. In DNS parlance, that
dot usually means, "don't add anything after this." So, when DNS is
trying to resolve the actual IP, it tries to look up "realname" with
no domain, and eventually times out. If you change this to:
samba-tool dns add dnsserver mydomain.org <http://mydomain.org>
newname CNAME realname.mydomain.org <http://realname.mydomain.org>
... then doing a "dig" or "ping" or whatever seems to work correctly.
I may be doing this wrong, but at least this is how I got it to work.

I haven't tried the above myself, but it seems you are
adding it the
wrong way around. i.e. it looks like you are saying
that the
canonical name of "centos" is "debian" instead of what
you want (i.e.
that the canonical name of "debian" is "centos".)
i.e. it looks like you now have this situation:
centos IN A 192.168.1.11
centos IN CNAME debian
Yes, I did wonder about that and did try it the other way
around. That
resulted in a new record as follows;
Name=debian, Records=1, Children=0
CNAME: centos. (flags=f0, serial=21, ttl=900)
But it still doesn't resolve.
OK, then try specifying the FQDN for "centos" when you add the
CNAME
record. From the output above it looks like it's adding a
CNAME to
"centos." instead of "centos.example.com
<http://centos.example.com>".
Also try:
dig @192.168.1.254 <http://192.168.1.254> debian.example.com
<http://debian.example.com>. IN CNAME
If everything is set up correctly you should get something
like this:
[...]
;; QUESTION SECTION:
;debian.example.com <http://debian.example.com>. IN
CNAME
;; ANSWER SECTION:
debian.example.com <http://debian.example.com>. 3600 IN

[...]
Ok, I used;
samba-tool dns add 127.0.0.1 example.com <http://example.com>
debian CNAME centos.example.com <http://centos.example.com>
a query now returns;
Name=centos, Records=1, Children=0
A: 192.168.1.11 (flags=f0, serial=2, ttl=900)
Name=debian, Records=1, Children=0
CNAME: centos.example.com <http://centos.example.com>.
(flags=f0, serial=23, ttl=900)
and 'dig @192.168.1.254 <http://192.168.1.254> debian.example.com
<http://debian.example.com>. IN CNAME' returns;
[...]
;; QUESTION SECTION:

However, neither 'debian' nor 'debian.example.com
<http://debian.example.com>' resolve to an IP, yet the output from
dig implies the entry is correct? Of course, 'centos' does resolve.

Well I too got dig, on the server, to produce the correct output but the
hostname (either short or fully qualified) would not resolve to an ip
address from _any_ clients. I'm using the internal dns server by the way.
As I mentioned, I bodged it by just adding would be CNAME entries as A
records. Not orthodox but it works for now.
