...d CentOS 6 for domain controllers and with Bind bundled in this distro was impossible to use dynamic DNS updates. And because I don't like using compiled SW on production servers, we used Samba internal DNS, which worked well (dynamic updates). With one non default setting - allow dns updates = nonsecure. Because there is something wrong with our computers, because some of them can secure update their A record, but some of them not. If I try rejoin affected computer to domain (unjoin, delete computer account, join again), secure update works. It's also strange, because affected computers are...

I'm alerting that the documentation found https://www.samba.org/samba/docs/man/manpages/smb.conf.5.html#ALLOWDNSUPDATES Describes the options available for 'allow dns updates' to be 'disabled', 'secure', 'enabled' or 'nonsecure'; --DNS updates can either be disallowed completely by setting it to disabled, enabled over secure connections only by setting it to secure or allowed in all cases by setting it to enabled or nonsecure. I have just verified that 'enabled' does not operate as a synonym for 'nonsec...

...to take care not to damage Samba database, so every time I made on DC's I first stopped Samba AD service on all DCs, then made snapshots of that VMs and than started them again. So everything was consistent. But maybe something went wrong during this process. But it's very interesting, that nonsecure dynamic DNS work with internal DNS with all clients and secure ones with only several clients, but also with Bind. Secure DNS updates never worked well on our environment. I made some tests in time after upgrading from Samba 3 in 2015 which resulted to setting option "nonsecure" in smb.c...

...168.30.2, 192.168.30.6; dc1 (192.168.30.2) / dc2 (192.168.30.6) are domain Controller with bind_dlz DNS, dc2 is update via axfr dc1 ist dns master and where I see the errors. client 192.168.30.175#55454: update 'samdom.example.com/IN' denied and where i have add 'allow dns updates = nonsecure' to smb.conf without solve the problem. I think the client is talk to bind directly without using samba. I have also find and try https://wiki.samba.org/index.php/Configure_DHCP_to_update_DNS_records_with_BIND9 but when I try to update the dns zone from the router on dc1 i get NOAUTH error....

> Yes, it is a failure, but a failure of the script, it shouldn't print > all those Python errors, it should print something like 'No update > required' for each attempted update and then 'No updates required' Yes, I understand. samba_dnsupdate --verbose --all-names --use-samba-tool gave reasonable output. But samba_dnsupdate --verbose --all-names only just throws ;

I just tested samba_dnsupdate --verbose --all-names on our test domain. Samba 4.8.2 from Tranquil IT on CentOS 7 and its Bind 9.9.4. And it just work. But with Internal DNS it threw ; TSIG error with server: tsig verify failure and Failed nsupdate: 2, same as in production domain. So you are right, Rowland, it's problem with Bind - Samba communication. But I don't know, why in test

Hello, everyone. To recapitulate the results of our research: 1) I can confirm Samba 4.8 and Bind 9.9.4 (distribution package) on CentOS 7 (tested od 7.5) work even with dynamic DNS updates without any additional fixes or need to recompile Bind package. I think it will work also on other RHEL 7 clones, so we should update Wiki page:

I have one more interesting thing. I copied DC01 to LAB environment. I demoted "dead" servers DC02X and DC03X. After that I changed DNS backend to BIND. Now samba_dnsupdate --verbose --all-names run as expected (without TSIG errors). Also, I have one problematic client joined to domain during troubleshooting and it cannot do DNS update with Bind. So I also cloned it to LAB like DC01.

The update with the dhcp script work for now. I'm not sure if it works since I add "allow dns updates = nonsecure" or if it works after a service restart. I will test if it is useable for me.

Thanks Rowland, I tried that just now, but as soon as I restarted samba, the error occurred again a few seconds afterwards. The good news, I suppose, is that it's easy to reproduce - each time I restart samba I get the error :) But, it wasn't helped by adding "allow dns updates = nonsecure" to smb.conf on one of my DCs. I wonder if there is some error being flagged by the internal DNS sync mechanism, instead of the port 53 listener - which would explain why it happens when I start up samba, and why I can't see any relevant traffic using tcpdump..

I have done the bind config like Rowland's post. The problem is still the same. windows: nslookup foo -> nxdomain nslookup foo. -> ip of DC in linux both is return an ip Whats about the file named.conf.update in samba/private? I have try to include in named.conf or in dlz "AD DNS Zone"{ ... include ../named.conf.update } without success. My bind log errors like

...wing: If you have chosen the internal DNS as backend for your environment, there are only two options that can be added to your smb.conf, to control the behaviour of DNS at this point: # Don't allow any updates | allow unsigned updates | only allow signed updates allow dns updates = False | nonsecure | signed # If recursive queries = yes is set, the following is also needed dns forwarder = <ip addr of external dns server> I think the page needs some urgent editing because self contradictions merely create confusion.
