> Which  means that you probably never ran the aptly named
> 'samba_upgradedns'Of course I ran this. Many times. I'm not

https://wiki.samba.org/index.php/Joining_a_Samba_DC_to_an_Existing_Active_Directory
https://wiki.samba.org/index.php/BIND9_DLZ_DNS_Back_End
https://wiki.samba.org/index.php/Testing_Dynamic_DNS_Updates
https://wiki.samba.org/index.php/BIND9_DLZ_DNS_Back_End#TroubleshootingAnd tried
everything possible. Writing mail to lists is the last instance for me...On
every of our DCs:

Failed update of 28 entries

But it's nothing new, that errors I've seen from 4.2 until now.

server in SOA (the very first provisioned DC), but that DC and all another DCs
are NS for domain zones.
But if you demote that first DC (primary in SOA), the record for that DC will
remain in SOA. I tested it in lab environment and Bind threw errors because of
that.
Moreover samba-tool domain demote remain many things in DNS and you have to run
samba-tool domain demote --remove-other-dead-server= also. And manually delete
rest for sure. Thats pain.
And I don't know how others, but I tested FSMO transfer on 4.7 (both DCs)
and also 4.8 (both DCs) at it also didn't performed well. I hit some kind of
timeouts during transfer and I had to run it 7 times to transfer all roles.It
was really painfull in our environment. But it's quite old (from Samba 4.2)
a classiupgraded, so quite different than default provisioned.Actually, I'm
really glad our domain works at least with nonsecure internal

How do that internal server with "nonsecure" options? As I wrote in
the first mail, I have no problem with forcing Bind to do thing insecure.Jiri

[Samba] Samba 4.8.4 + BIND 9.9.4 - possibility of nonsecure DNS updates

; TSIG error with server: tsig verify failure

Mayabe update/setup your TSIG key. 
https://access.redhat.com/documentation/en-us/openshift_enterprise/2/html/puppet_deployment_guide/generating_a_bind_tsig_key

Im also wondering why RH is using : '--disable-isc-spnego'

I never said you were stupid, but I asked how you upgraded to Bind9 and
you never mentioned 'samba_upgradedns'

Where ?? It has worked faithfully for me for the last 5 1/2 years.

OK, try this:

samba_dnsupdate --verbose --all-names --use-samba-tool

Yes that is a pain, you need to manually remove it with samba-tool.
Not sure, but I think the latest Samba removes it when a DC is
demoted.

And manually delete rest for sure. Thats pain. And I don't know

As I said, a lot of the above has been fixed in the latest Samba
versions.

Not sure about that, do your DC's point to themselves as their first
nameserver or another DC ?

Good catch Louis, that rang a bell and the answer is because you cannot
run a Samba AD DC on red-hat with distro packages, so they stop updates
(Don't ask why, I don't know)

see here:

https://wiki.samba.org/index.php/Using_BIND_DLZ_backend_with_secured_/_signed_DNS_updates

So in answer to the OP, sorry, but I missed/forgot this and the answer
to your problem is, you will have to rebuild the Bind9 rpm.
