Package: samba-libs Version: 2:4.12.3+dfsg-2 Severity: critical Justification: breaks the whole system
The new samba-libs package changes the soname of libndr from libndr.so.0 to libndr.so.1 without reflecting this change in the package name. sssd-ad-common has a dependency on samba-libs (>= 2:4.11.5+dfsg) and links to libndr.so.0. When the samba-libs package is updated and libndr.so.0 disappears sssd fails to start, which then makes a system's remote users unavailable. (Worse, this doesn't happen until the next time sssd restarts--which may not be until the next reboot.) It's not clear why the samba-libs package doesn't include the so number, but at the very least it needs a set of dependencies to avoid breaking sssd-ad-common.
