Today, I merged some changes to the trunk which significantly change how the Calendar Server is configured. If you have a working configuration and do an update, you'll need to make some changes. I've updated the README file and the web site to reflect these changes, and documented them as well as I could. In particular, you'll want to check out: http://trac.macosforge.org/projects/calendarserver/wiki/QuickStart http://trac.macosforge.org/projects/calendarserver/wiki/DirectoryService http://trac.macosforge.org/projects/calendarserver/wiki/RepositoryXML Note that repository.xml no longer contains account and authentication information. That has now moved to caldavd.plist and the new directory service functionality. The new directory service functionality now allows for different back-ends for provisioning principal information, and neatly contains all of that in one place. You no longer have different repository.xml files depending on the back-end. Back-ends include Apache user/group files, an updated XML file format, and OpenDirectory. Regards, -wsv
