[CalendarServer-dev] Unable to connec tto owncloud contacts using caldavclient library

I am unable to connect to a owncloud carddav account using runshell like I am able to do with a calendar server installation. Has anyone had any success? I tried: ./runshell.py --server https://unhammer.org/owncloud/index.php/carddav/principals/skarra/ --user skarra --pswd Initially there is no message or error. All commands fail with a 405 Any clues?
