Had an incident where around 50 of 70 users were deleted from an ifolder slave. The ifolders they had were then orphaned. The next day the users were synced back into ifolder, but the folders had to be associated manually. Any ideas on why this would happen or a better way to repair if it happens again? Below is snippet from simias.log showing what happened for a single user. We were running ifolder and have patched to
