CalDav and Mulberry


Zimbra 5.0 Supports the CalDAV standard. CalDAV is a protocol allowing calendar access via WebDAV. CalDAV models calendar events as HTTP resources in iCal format, and models calendars containing events as WebDAV collections.

This allows users to publish and subscribe to calendars, share them collaboratively, synchronize between multiple users and synchronize between multiple devices. The CalDAV standard is an implementation of iCal(The standard, not the client) on a WebDAV server.

When using CalDAV, all of the users calendars are added to Mulberry.

Originally developed for the Apple Macintosh, versions now exist for that platform as well as Microsoft Windows and Linux using the X window system. Mulberrys strengths include strict compliance with internet standards such as IMAP, LDAP, IMSP, ACAP, and iCalendar, and support for IMAP disconnected operation.

Macintosh: Zimbra Connector for iSync

The Zimbra Connector for iSync syncs Zimbra calendars to iCal for Tiger (10.4) and Leopard (10.5). However, the sync is done using SOAP and not CalDAV. The Zimbra Connector for iSync does not support Mulberry, so any sync must be done to iCal(the application). Users are encouraged to use CalDAV whenever possible. Native CalDAV is supported through iCal in MacOS 10.5 only.
