Starting from version 3.1, Kolab is fully supported by CalDAV-Sync and CardDAV-Sync
Just enter the name of your server along with your username and password. Address books and calendars will be discovered automatically.
- Server URL: <servername>/iRony
- Use SSL: check accordingly
- Username: your login name
- Password: your password
If you changed the iRony URL in your apache config (for Max OS X compatibility for example) you have to change the Server URL accordingly.
See the instructions for CalDAV-Sync, with CardDAV-Sync it works exactly the same way.
Birthdays/anniversaries are not synchronized via CARDDAV. See the issue #2142 in Kolab's issue tracker.
