But the current situation, in which samba upgrades randomly render systems unusable is, in my opinion, much much much worse than an overly strict dependency. Fundamentally the problem is that you're promising future compatibility but not providing that. One way or another samba-libs either needs to not suggest that linked binaries will work with future versions, or make sure that they do.

Heck.

I did some modifications to the packaging, added the right Breaks: against
an "old" sssd-ad, which should close this very bugreport.

But.  And this is a big fat BUT.

I also adjusted list of samba-libs files in samba-libs.install to include
all sonames explicitly.

And this revealed one more issue here, now with samba 4.17.  Where, the
same libndr.so again, has changed soname from libndr.so.2 to libndr.so.3!

And it looks like *this* is what you're talking about now, once 4.17 with
this new libndr.so.3 hits unstable.

*Sigh*.

So now, samba-libs breaks not only bullseye sssd-ad, but also *bookworm*
sssd-ad!

So:
  samba-libs 4.13: libndr.so.1
  samba-libs 4.15: libndr.so.2
  samba-libs 4.17: libndr.so.3

and this is what we're facing now, 4.16=>4.17 update breaks things again.
and this new breakage went unnoticed, and I knew nothing about the soname
change before this very moment.

Andrew, can you share some info about the new 2=>3 soname bumb in 4.17?

I wonder if we should provide old libndr.so.1 and libndr.so.2 interface
in samba-libs forever... this shouldn't be that difficult.
