I have just installed calendarserver, and I can't access any calendars. On the client side I use Iceweasel, and I have tried both ICS and CalDAV; in both cases I find messages in the log saying the X-Authorize-As header is missing: ICS - client: [Exception...

So, obviously I haven't set everything up as required. Is there a good desription of how to do this anywhere?
