I solved the problem with a small daemon and grant external.
It was not easy for me since I am not a C programmer.
It would be nice if there would be some examples in C or Python in the
future.
regex support for grant rules would also be nice.

Use external. You can create any rule you can think of with that.

I want an external server to be able to update all the hosts (A) records
inside the example.de domain.
But i don't want that the external server can create subdomain entries
inside the example.de domain.
Is this possible? What grant/deny rule must i use?

Step back and tell us what you are attempting to achieve.
e.g. I want my hosts to be able to update their address records.
grant admin-key subzone ANY;
grant * self . A ;
and use SIG(0) to sign the updates. The admin adds the public KEY record for
the machine
using ‘admin-ke
But i don't want to specify all possible hostnames in the update-policy

there are more than 350 hosts in the example.de domain.

Allow this:

update add host2.example.de 86400 a 2.2.2.2
Deny this:

Right now we have our external view for adi.com set up to use

Hi Eric,
Depends on how long you can live without dynamic updates, and how many
dynamic updates it's acceptable to lose in the event of a master failure.
Journal files are synced every 15 minutes, so in the event of a master
failure (in a single-master situation), you've lost at most
(admin’s, vmware,
autosys) to use dynamic updates with nsupdate for all tasks. Everything works
dandy but a simple question remains:
If the primary goes down for whatever reason, how can we quickly continue to
update our DNS records on the secondary? What are the options?

But one A record doesn't "override" another with the same name, anyway.
If a dynamic update just adds a new A record, both would coexist. The
old one could be dynamically deleted in the same update transaction.
If so, can
