Kerio CalDAV and CardDAV setup tips

This is a quick reference guide to configuring Kerio Connect 7.2 with a 10.6.7 machine + an iPhone.

CalDAV for iCal 4.0.4:
username user@server.example.com
server https://server.example.com/caldav/

CalDAV for Lightning 1.0b2:
username user@server.example.com
server https://server.example.com/calendars/server.example.com/user/Calendar

CardDAV for Address Book
username user(server.example.com)
Yes the server is in parentheses.

server address https://server.example.com:443
Check the port in your admin page.

Configuring CardDAV within the iPhone will not work. You must use the iPhone Configuration Utility. If you’re savvy enough to have configured your own services so far this utility is a breeze to use. Fire it up, go to Configuration Profiles and fill out the General and CardDAV sections. In case you’re pulling from two different servers or with two (or more) different usernames, it’s easy to add multiple sets of settings. After you’re done, connect your phone and click the install button.

I am kind of stunned at how well this is working compared to all other Calendar and Contact syncing apps I’ve used. I used to have to wait for Google Calendar to finish writing (over the network) on my phone or I’d lose data, and every form of contact syncing other than the paid mobileme service has lost contact data including phone numbers, custom labels, etc. Syncing via iTunes with Google Contacts periodically duplicates some contacts. Syncing contacts using exchange is a nightmare, it dumps all custom labels and all but ~3 of the phone numbers per contact.

This solution not only maintains my contact entries perfectly but also syncs over the air. When inputting calendar data on my phone – which I do constantly – I don’t have to wait for network operations to finish, I just put in the data and sleep it. On top of all this I synced the contact data to my phone and after verifying it’s accuracy deleted the old information, expecting to have to reconfigure favorites. I didn’t. The transition is seamless. I can’t guarantee that for everyone, so make your backups first!
