Bug#1004729: bind9-dyndb-ldap: fails to load dyndb-ldap backend

[l3mm.0x]

Package: bind9-dyndb-ldap
Version: 11.6-3
Severity: grave
Justification: renders package unusable

Dear Maintainer,

after an upgrade from buster to bullseye my previously working bind9-dyndb-ldap
installation dosn't work anymore.

It seems that there is something wrong with the dependencies to the package
bind9-libs.

named log:

The package bind9-libs lists a newer version about the shared object file.

(correct an error of my precedent message: On Debian 11 Bullseye, bind9 version is actually 9.16.27 not 9.16.22)

It is impossible to use bind9-dyndb-ldap ( version 11-.6.3) on debian 11 bullseye because it try to load libdns-9.16.15-Debian.so and libics-9.16.15-Debian.so

whereas the actual version of this libraries is 9.16.27.

Make a 'ln -s' (ls -s libdns-9.16.15-Debian.so libdns-9.16.27-Debian.so) fail:
