talloc, tevent and tdb are all backwards-compatible so far.
I can't say for any future release of those libs, maybe someday
some incompatibiluty will happen. But during a few recent samba
releases (4.13..4.18), the ABI in these libs is completely
backwards compatible.

Speaking of ldb, things are a bit more interesting in there.
But the interface is still - by fact, not by contract - is
backwards-compatible in parts needed by sssd.  More recent
samba needs more recent libldb, including minor/stable
releases, since quite often stuff is fixed in libldb and
the new interface is immediately being used by samba, esp.
the ad-dc code.

There's another issue with sssd: it is libndr.so soname bump
which happened a few times during recent samba releases.
This lib is also used by sssd.  But here, actual user-visible
ABI of the library hasn't changed, so it's okay to create
temporary compat links libndr.so.1 and libndr.so.2 pointing
to libndr.so.3.
