Diagnosis hints
To narrow possible causes of CalDAV problems in small calendars, (1) set preference calendar.debug.log.verbose to true, and (2) click right on calendar in the Calendars pane to reload it. The xml CalDAV messages will be shown in the error console (and in the startup command line shell). (Set pref via Options / General / Config editor, right click New / Boolean to add it.)
Zimbra Notes
Password does not have to be supplied in URL. For example:
http://zimbrahost.example.com/dav/USERNAME/Calendar
To find version of server from Zimbra Web UI, go to help, search for 'version'.
Sunbird/Lightning 0.9 now asks for both VEVENTS and VTODOS from a CalDAV URL. Zimbra version 5.0.8 or later is required to fix problem described in bug 438642, though there is a patch at that bug to workaround the problem that is easy to apply by hand (the file is in the installed /js/ directory). As of this writing, the testzimbra demo server is only running ZCS 5.0.5, so it is broken and requires the workaround.
Zimbra tasks: As of Zimbra 5.0.5, the .../Calendar url does not include tasks, and the .../Tasks url does not work for CalDAV (there is a corresponding url for ics/WebDAV -- in the Tasks tab, in the left column Tasks folder, right click and click the 'sharing' menu item to display it).
