Comment 5 for bug 1781991

Are you saying that you've checked and can confirm that 16.04 and 18.04 are affected? If so, please could you confirm the package versions of sssd in which you have verified that the bug is present?

Depending on the fix it may be easy to backport to fix 16.04 and 18.04. But are users actually impacted enough that this would be useful? See https://wiki.ubuntu.com/StableReleaseUpdates
