I've seen a workaround from Cyrus on how to deal with this: <http://lists.apple.com/archives/ical-server/2007/Nov/msg00036.html> but it hasn't worked for me. guess what. in CalendarServer/contrib/tools/ there is a tool called fix_calendar. Description: This utility will add xattrs to the specified directories and their contents to make them appear to be calendars and calendar resources when used with iCal Server. It can be used to fix xattrs lost as a result of restoring an iCal Server document root without properly preserving the xattrs. from the terminal you would run:

./fix_calendar path-to-calendar

and bam! fixed xattrs found this while browsing the code. :) -John Daniele -- Daniele Procida Web Officer Cardiff University School of Medicine Tel.: +44 29 2074 2144
