Which is preferable to use from the CalendarServer trunk?
This is for a CalDAV server, with users/groups/etc in an OpenDirectory server (accessed through DirectoryServices)

The appleopendirectory version is the one that's been around for a while, so it's potentially more stable, but the startup time can be long if your directory has a large number of users/groups (because this code reads all directory records in from the OD server -- and actually does this *per* calendar server "slave" process). The cachingappleopendirectory version not only faults records in only as needed, but uses memcache to share those records amongst the calendar server processes. We are still evaluating the performance benefits of this new version. Note also that resource delegation (being able to specify which users are allowed to be delegates for a resource or location) is not yet supported in cachingappleopendirectory yet. ~morgen
