Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.12 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

Error: [13][Permission denied] Status in linux package in Ubuntu: Incomplete Bug description: If an attempt is made to mount an overlay filesystem over the /var/log directory, this causes sssd to refuse to start up. The startup fails at the point where sssd attempts to write to its logfiles: sssd: Could not open file [/var/log/sssd/sssd.log]. Error: [13][Permission denied] sssd is running as root, and should have no problem writing to logfiles. Removing the -f option from sssd causes sshd to not attempt to write to /var/log/ssshd/ssshd.log and sshd startup succeeds. Running sssd without any flags logs to syslog, and this works correctly, logging to /var/log/syslog on the overlayfs filesystem. Removing the file /etc/apparmor.d/usr.sbin.sssd causes sssd to start up correctly, logging to the overlayfs /var/log/sssd directory without an issue. Looks like the apparmour configration for sssd breaks when an overlayfs is present.
