Public bug reported:
Because /var/log/syslog gets bloated with sssd apparmor related
messages, I put the following in /etc/apparmor.d/local/usr.sbin.sssd
then I changed sssd from 'complain' to 'enforcing' mode. I put this on
a heavy sssd vm running freeipa server that also is running the gui with
mate. I can't promise I found all the cases, but I don't see any
'apparmor' messages in the logs on the freeipa servers after a couple
days.
signal (send) peer="/usr/sbin/sssd//null-/usr/libexec/sssd/sssd_pac",
/usr/sbin/sssd ixr,
/usr/libexec/sssd/sssd_be ixr,
/etc/krb5.conf.d/** r,
/etc/krb5.conf.d/ r,

/usr/libexec/sssd/ldap_child ixr,
dbus send bus="system" path="/org/freedesktop/systemd1"
interface="org.freedesktop.systemd1.Manager" member="GetDynamicUsers",
There are thousands of varied examples you'll see in the logs, generally along
the lines of
Jun 23 06:41:55 registry2 kernel: [56263.674613] audit: type=1400
audit(1592912515.202:2329356): apparmor="DENIED" operation="signal"
profile="/usr/sbin/sssd" pid=1058 comm="sssd" requested_mask="send"
denied_mask="send" signal=term
peer="/usr/sbin/sssd//null-/usr/libexec/sssd/sssd_pac
I'm not a 'deep interest' apparmor dev, no doubt the above list could be
improved.
