No, I have dhcp and a full bind9 serving master zones forward and reverse,
with exception of the _msdcs... SOA, which I let only forward and it seems

The configs are static, no dynamic updates, and I generate the dhcp config
and the zones per script, if something changes.

In all the complexity you mean it exists in my unsupported configuration you
will laugh, but I try to keep things simple and stupid, so I can grasp all
the little I do :)

- First I wish to stay with a single dns name space with only a part of it
in the AD, but BIND_DLZ should serve a separate sub-zone for the AD.

- Doing dns and dns-updates trough samba could be a source of error and
frustration, as I read sometimes in questions here in the mail list or other
places in forums.
So I say to my clients to not do dns-updates, because I have already all
possible in DNS.
Equally positive I feel that no service is trying to modify configurations
of another service. I simply avoid this and the need to handle with special
kerberos user-services and keys, or to temper with apparmor is gone too.

- I sniffed at the beginning with dns_update, which records and SOA samba
supplementary needs on this machine, and this is an one time addition to the
zones in bind.

- I learned afterward, which DNS records should be added, if I join a second
DC to the AD.
- It seemed to me (reading different postings), that samba still has a bug
with doing this automatically, so one has anyway to add the _ldap.. ,
objectGUIDs addresses and the other records of the new DC himself.

So, I see it really simpler this way.
I'm sorry, that this will be always a source of discordance here by any
other question, related or unrelated to DNS.
I still do not think that the original problem was caused by the program
which DNS serves, otherwise it would have disturbed all other test-clients.
