[Pkg-samba-maint] Bug#1076196: samba-ad-dc: Samba AD-DC does not start due to missing files

[Béla Becker]

Package: samba-ad-dc
Version: 2:4.17.12+dfsg-0+deb12u1
Severity: normal
X-Debbugs-Cc: becker.bela at keglo.hu

Dear Maintainer,

The change due to #1051770 which moved crucial domain controller files
to the previously optional metapackage has caused our Samba domain
controller to fail to start. So far a minor inconvenience, one could
blame us for not having samba-ad-dc installed.
However, installing the samba-ad-dc package did no fix the problem,
because for some reason the older package from stable was selected
(samba-ad-dc 4.17) instead of the one in the backport repo. It is
necessary to specify the version to have APT install it.

To avoid existing systems breaking I would like to recommend either
setting a hard dependecy between versions of samba-ad-dc and samba to ensure
that the older samba-ad-dc (<= 4.19) metapackage is not installed alongside
the newer samba (>4.20) package, or reverting the change due to #1051770


The following command outputs show the issue: samba-ad-dc 4.20 is not
selected alongside samba even though it had since been installed.
