There appears to be a problem with sssd 1.9.4 on Ubuntu 12.04 server. if
apparmor is installed it takes a very long time to install via apt-get
and then will not start correctly, it hangs forever and if you stop it
with ctrl-c, it then claims to have started but hasn't.
It does not matter if you put apparmor into complain mode, it still will
not start, or if you try to stop or restart sssd it just hangs. The only
cure seems to be to totally remove apparmor with 'apt-get purge
apparmor', sssd then works correctly.
I got sssd from here:
