|
|
*
|
|
* - / base of Cal|Card|GroupDAV tree, only certain clients (KDE, Apple) can autodetect folders from here

* - /principals/ principal-collection-set for WebDAV ACL
|
|
* - /principals/users/<username>/
|
|
* - /principals/groups/<groupname>/
|
|
* - /<username>/ users home-set with
|
|
* - /<username>/addressbook/ addressbook of user or group <username> given the user has rights to view it
|
|
* - /<current-username>/addressbook-<other-username>/ shared addressbooks from other user or group
|
|
* - /<current-username>/addressbook-accounts/ all accounts current user has rights to see
|
|
* - /<username>/calendar/ calendar of user <username> given the user has rights to view it
|
|
* - /<username>/calendar/?download download whole calendar as .ics file (GET request!)

* - /<username>/inbox/ scheduling inbox of user <username>

* Shared addressbooks or calendars are only shown in in users home-set, if he subscribed to it via his CalDAV preferences!
