Help requested calDAV and cardDAV integration

[macsimus]

I used to have Owncloud installed. It was mainly used for syncing my calendar between devices. However it is a hefty software for rpi.
Decided to install Radicale instead. It is a very light weight alternative.

It is supposed to be the easiest installation?! However I can't make neither the Android device or iCal see my xbian server. I must be missing something.
Has anyone got this working?
Anyone can maybe paste their working config file?
