Probably, all DC's are authoritative for the domain:

Failover DC did not work when Main DC failed
My reverse zones have PTR records. Though I don't have NS records for all
of my DC's. I guess that needs to be manually created.
Also, you don't have any CNAMES or domain overrides pointing to a single
DC? Perhaps Bind is pointing to another internal DNS server, and then to a
public DNS?

Here's a way to test failover from a Windows client:

SOA record in Samba Internal DNS
Hi. I'm running Sernet Samba 4.7 on Ubuntu 16.
I noticed that when my first DC went away, I had problems. The SOA record
for the domain still points at that first DC.
I found, in this entry from 2014 (
https://lists.samba.org/archive/samba/2014-August/184301.html) that
"Windows AD servers actually 'lie' about the SOA record, and always say
that it points to themselves. So in a

Checked and both DCs pass all tests:-
host -t SRV _ldap._tcp.mydomain.com.
host -t SRV _gc._tcp.mydomain.com.
host -t SRV _kerberos._udp.mydomain.com.

Failover DC did not work when Main DC failed
What do you see/get when you run:
dig NS $(hostname -d)
With 2 dc's you should see 2 records.
In the past this was a bug at samba joins so only 1 NS record existed.
Worth to have a look at.
And adding this to /etc/resolv.conf:
options timeout:2
options attempts:3
options rotate
Also might help.

Louis

Samba + BIND9 DLZ. DNS dosen't resolve FQDN, only short hostname
Thank You Rowland. I did it like You say, killed avahi, added the record
without domain suffix, but nothing changed, and the record seems no
different compared to other records added with the suffix some time before.
My Samba DNS record looks like this (and I see nothing special in there):
Name=, Records=3, Children=0
SOA: serial=39, refresh=900, retry=600, expire=86400, minttl=3600,

DNS /16 reverse zone issues with children and octets
Hello Samba List,
I have 2 problems with dns - seeing the child entries and a zone with an extra octet.

samba_dnsupdate
Guys, what i noticed.
Look at this.
Refused- 1/3/0 (Class 254) ( /24 )
Paully used /16
update 1/3/1 (Class 254) CNAME V-RDS02.mydomain.com
CNAME ?
And, if he uses in his example
samba-tool dns add dc3 mydomain.com V-RDS02 A 130.130.0.252
A record was used.
Is resolv.conf checked and it is sure in pointing to the correct DNS of the AD first?

Samba fsmo/demote/unjoin trouble after crash
Hi all,
i've got initial setup on DC1 (4.0.1)... all working good and flawless

DN lists have different size: 4065 != 4029
Hello,
dc3 = principal DC
dc4 = secondary DC
I had this problem last month after updating samba to version 4.10.x. and
also the schema from 45 to 69. But it looked like it had been corrected.
Today I noticed that on dc4 there are computers that are not on dc3.
I updated:
4.7.x to 4.8.x
4.8.x to 4.9.x and only after that I upgrade to 4.10.x version.
When I run these commands:

Odd behavior since upgrading to 4.9.6
About a week and half ago I upgraded from 4.0.12 to 4.9.6. Overall, things are functioning.
However, I have come across several strange behaviors and wandered if anyone else has noticed similar behavior on 4.9.6 or has any suggestions of what might be occurring.
As background information, I have 3 DCs (dc3, dc4 and dc5) -- all running the same version (4.9.6) and all have the same configuration;
