Comment 9 for bug 1910611

Performing the verification on Groovy:

First, confirming that the current sssd manifests the bug:

# apt policy sssd
sssd:
  Installed: 2.3.1-3ubuntu2
  Candidate: 2.3.1-3ubuntu2
  Version table:
 *** 2.3.1-3ubuntu2 500
        500 http://archive.ubuntu.com/ubuntu groovy-updates/main amd64 Packages
        100 /var/lib/dpkg/status
     2.3.1-3 500
        500 http://archive.ubuntu.com/ubuntu groovy/main amd64 Packages
# aa-enforce sssd
Setting /usr/sbin/sssd to enforce mode.
# systemctl restart sssd.service
Job for sssd.service failed because the control process exited with error code.
See "systemctl status sssd.service" and "journalctl -xe" for details.
# dmesg | grep DENIED
[ 49.513861] audit: type=1400 audit(1611583630.788:14): apparmor="DENIED" operation="open" profile="/usr/sbin/sssd" name="/etc/sssd/conf.d/" pid=1876 comm="sssd" requested_mask="r" denied_mask="r" fsuid=0 ouid=0
[ 49.514342] audit: type=1400 audit(1611583630.792:15): apparmor="DENIED" operation="open" profile="/usr/sbin/sssd" name="/usr/share/sssd/cfg_rules.ini" pid=1876 comm="sssd" requested_mask="r" denied_mask="r" fsuid=0 ouid=0
...

Now, confirming that the sssd on -proposed fixes the problem:

# apt policy sssd
sssd:
  Installed: 2.3.1-3ubuntu3
  Candidate: 2.3.1-3ubuntu3
  Version table:
 *** 2.3.1-3ubuntu3 500
        500 http://archive.ubuntu.com/ubuntu groovy-proposed/main amd64 Packages
        100 /var/lib/dpkg/status
     2.3.1-3ubuntu2 500
        500 http://archive.ubuntu.com/ubuntu groovy-updates/main amd64 Packages
     2.3.1-3 500
        500 http://archive.ubuntu.com/ubuntu groovy/main amd64 Packages
# systemctl restart sssd
# echo $?
0

This verifies that the Groovy sssd package in -proposed fixes the bug.
