FS1 Samba4 Upgrade

Resolved after 19 hours 35 minutes, on June 14, 2016.

postmortem Jul 31, 2018, 05:07 PM UTC

The upgrade to 4.2 failed. After upgrading the packages and rebooting the server, I was unable to connect due to the following error: The primary group domain SID () does not match the domain SID() for phrgadmin(). Rolling back to the pre-upgrade snapshot appears to have resolved the connectivity issue. Research appears to be inconclusive for how to resolve this problem.
