Setup ICal Server 3 and Contacts

I want to set up a shared calender for my family with Lion Server but:

-the only option i get in is to add locations and rescources witch no one can see except for the represtatative.

-If i add the webserver with webcal it works just fine with a calender for every user but not a shared one

-if i want to add the calender with ical i get the error Message that there is no running ical Server or i entered the wrong url.

We Have very slow internet around here so it would be important that the ical Account works that you dont need the slow webcal.

Thanks for your help :-)
