[Pkg-samba-maint] Bug#1107139: samba-libs: DLZ module for bind9 version 9.20.x is missing, which breaks --dns-backend=BIND9_DLZ in trixie

[Steven Monai]

Package: samba-libs
Version: 2:4.22.1+dfsg-1
Severity: important

Dear Maintainer,

Testing Samba AD provisioning in a freshly installed Debian trixie 
machine, I discovered that samba-libs does not provide a DLZ module for 
the trixie version of bind9.

Steps to reproduce:

* Create a new Debian trixie virtual machine
* Install packages: samba, samba-ad-dc, bind9 (plus a few more)
* Provision a new AD domain, with --dns-backend=BIND9_DLZ
* Include /var/lib/samba/bind-dns/named.conf in /etc/bind/named.conf
* Restart services: samba-ad-dc, named
* Attempt to resolve the newly-provisioned domain's NS record
* Observe the resolver reports NXDOMAIN instead of the expected NS record

I see that /var/lib/samba/bind-dns/named.conf does not contain config 
lines for the version of bind9 in trixie (9.20.x), which I expect should 
look like this:

# For BIND 9.20.x
database "dlopen /usr/lib/x86_64-linux-gnu/samba/bind9/dlz_bind9_20.so";

Also, the file /usr/lib/x86_64-linux-gnu/samba/bind9/dlz_bind9_20.so 
does not exist, although there are files for earlier versions of bind9 
within that directory:

root at dc:~# dpkg -L samba-libs | grep -i dlz
/usr/lib/x86_64-linux-gnu/samba/bind9/dlz_bind9_10.so
/usr/lib/x86_64-linux-gnu/samba/bind9/dlz_bind9_11.so
/usr/lib/x86_64-linux-gnu/samba/bind9/dlz_bind9_12.so
/usr/lib/x86_64-linux-gnu/samba/bind9/dlz_bind9_14.so
/usr/lib/x86_64-linux-gnu/samba/bind9/dlz_bind9_16.so
/usr/lib/x86_64-linux-gnu/samba/bind9/dlz_bind9_18.so

Can this can be remedied in time for Trixie's release? Or is there a 
work-around or alternative way to get BIND9_DLZ to work in trixie?

Thank you,
-S.M.
