Configuring Evolution for CalDAV and CardDAV with Darwin Calendar Server

The correct settings to feed Evolution are:

Calendar:

Create a new CalDAV calendar with this URL:

https://servername.fqdn:8443/calendars/users/username/calendar/

Set "Username" in the GUI to your login username. (Replace "servername", "fqdn" and "username" in the URL, obviously.)

Example URL that works for me (my login username being "ch"):

https://server.local:8443/calendars/users/ch/calendar/

Address Book:

Create a new WebDAV address book with this URL:

https://servername.fqdn:8443/addressbooks/users/username/addressbook/

Set "Username" in the GUI to your login username as well. (Replace "servername", "fqdn" and "username" in the URL, obviously.)
