[Pkg-sssd-devel] Bug#854354: sssd prevents system booting up

[Jonathan McDowell]

Package: sssd
Version: 1.50.0-2
Severity: grave

I updated my stretch system this morning which led to it failing to
reach a login prompt; the system would start up and then avahi-daemon,
ModemManager and NetworkManager would all fail to start, then
systemd-logind would fail. This repeated in a continuous loop. Initially
suspecting ModemManager or NetworkManager I tried removing them (the
machine has wired ethernet, configured via /etc/network/interfaces), but
this did not help.

Looking at the errors provided by systemd in my logs led me to:

https://lists.debian.org/debian-user/2017/02/msg00025.html

which provided the clue I needed to try downgrading ssd from 1.15.0-2
(which was pulled in by the update this morning) to 1.14.2-1 (the
previously installed version). The machine subquently rebooted cleanly.

A coworker's machine was similiarly affected, and the same solution
worked there.

There seems to be a lack of errors in logs relating to sssd, but I can
try to provide any extra information that might be helpful. In
particular daemon.log contained many, many instances of:

apus systemd[1]: Looping too fast. Throttling execution a little.
