[Pkg-samba-maint] Bug#1099755: samba: samba recommends samba-ad-dc, why?

[Andreas Hasenack]

Package: samba
Version: 2:4.22.0+dfsg-1
Severity: normal

Dear Maintainer,

we noticed that a simple "apt install samba" now also installs
samba-ad-dc which pulls in all sorts of other dependencies like
winbind, libpam-winbind, libnss-winbind, and others, which weren't
there "before", and are not needed for an SMB file server.

This was introduced in 2:4.21.1+dfsg-2:
samba (2:4.21.1+dfsg-2) unstable; urgency=medium

  * d/control: add Recommends: samba-ad-dc for samba for now
    to avoid breaking existing installs
  * d/samba.postrm: stop unmasking of samba-ad-dc
    (it is already done in postinst)
  * d/samba.postinst,d/samba.maintscripts: remove samba-ad-dc
    startup files and stop the service (Closes: #1085617)

There used to be a Recommends in bin:samba for samba-ad-provision, but
that was dropped in 2:4.20.1+dfsg-2:
samba (2:4.20.1+dfsg-2) unstable; urgency=medium
  * move many files from samba package to samba-ad-dc package.
    From now on, samba-ad-dc isn't just a meta-package, it is actually
    needed for AD-DC functionality.  If you run AD-DC, please ensure
    that samba-ad-dc package is installed (it is not recommended by samba)
    Closes: #1051770
...
  * d/control: samba: no need to recommend samba-ad-provision


Why is bin:samba recommending bin:samba-ad-dc? That will make every
samba install, even simple file servers, have files and services for
ad-dc?
