samba - Jan 2012 - [Samba4] samba_dlz problem "loading configuration: already exists"

Hi,

I'm new to this list and Samba4, so may be this is a stupid question.
I've installed samba4 (4.0.0alpha18-GIT-7b42ceb) on a server in my home LAN
and have a problem with samba_dlz and bind (9.8.1-P1).

In the zone definition file for my LAN domain, I had configured the IP addresses
for several host names (e.g. printer, ...) with "A" records. This
worked perfectly fine in the past (e.g. "nslookup printer" returned
the IP address of my printer). After adding the following line in
/etc/named.conf according to the HOWTO:

include "/usr/local/samba/private/named.conf";

...I now get an error from samba_dlz:

named: samba_dlz: Failed to configure zone 'myzone.priv'
named: loading configuration: already exists

If I comment-out my zone in /etc/named.conf, Samba4 works fine (it can even
update the DNS database), but I can of course no longer access my devices, e.g.
nslookup printer returns:

aschweiz ~> nslookup printer
Server:		172.16.1.18
Address:	172.16.1.18#53

** server can't find printer: NXDOMAIN

What I already tried was to add my devices in dns_update_list, e.g. by adding a
line:

A    printer    172.16.1.16

However, then I get an error message when starting samba: "Failed DNS
update - NT_STATUS_ACCESS_DENIED".

Can anybody help me with this? How to add devices to the zone that Samba creates
in the DNS server?

Thank you,
Andreas

I have not tried this, but I believe you need to do something like this:

dlz "AD DNS Zone" {
   database "dlopen /usr/local/samba/modules/bind9/dlz_bind9.so";
};

Try using "samba-tool dns" to query/update the records.

I'm no expert but I also had problems with the dns updates. I added the 
line:

  tkey-gssapi-keytab "/usr/local/samba/private/dns.keytab";

to the options{} section of /etc/named.conf and all was well. There is 
some named:named ownership stuff to do for that keytab and the dns 
folder in the same directory. Not on the lan at the moment but I think 
it's explained in named.txt, also in the /private directory.

I think the you already have this if you:

include "/usr/local/samba/private/named.conf";
