I've installed and configured DCS on FreeBSD 7.0, having dealt with memcached and PyKerberos setup issues... iCal 3 seems to work fine. I can publish calendars to the server without incident. I can also browse collections just fine using a web client. But I am having trouble configuring Sunbird. I cannot seem to create, or subscribe to, any network calendars. I have been using the instructions at: http://trac.calendarserver.org/wiki/Sunbird to specify URLs like http://myserver:8008/calendars/users/myuserid/calendar http://myserver:8008/calendars/groups/mygroupid/calendar On the client side, Sunbird "lets" me create the calendar, but I always get an error icon by the calendar with a Tooltip message "The calendar <newcal> is momentarily not available". If I then try to write to the calendar, the server looks like it is going to write -- I see a PUT, then "Writing request stream," then "Writing to file", but then: [-] [twisted.web2.dav.method.put_common#error] Rollback: commit and the event is not written to the calendar. I get no server errors on startup, other than "invalid GUID in accounts XML" warnings... Help! -- John Berliner john@johnberliner.com
