Group calendar on wiki doesn't work but individual calendars do.

Question

We have 10.6.3 server running as a OD master and I was looking to use the group calendaring feature of the wiki server. I go to the server using a web browser, sign in, and create a new wiki called "test". I then go into settings for the wiki and enable Calendar as one of the services. I save the settings and get a calendar link at the top of the page for the wiki. When I try to view the calendar I get the message in the middle of the page that says "Getting events from server ..." This never goes away.
When I go to view the calendar for my user, it comes right up. It seems that I have things configured well enough for the web and iCal servers to talk to each other, but something is going wrong with the wiki portion.
Since we are dealing with CalDav I started by using a web browser to diagnose the problem. I go to https://server1.jaxon.private:8443 and I can see that CalDav is working and I get the proper output. I try https://server1.jaxon.privat:8443/principals/users/username and I get all sorts of great info about the user. Finally I try https://server1.jaxon.private:8443/principals/wikis/test and I get an Internal Server Error. It makes sense that the webpage isn't working since the CalDav server isn't happy.
The site access log has the following entries when I try to visit the calendar:
10.0.1.20 - - [24/May/2010:14:44:48 -0600] "POST //server1.jaxon.private//server1.jaxon.private/RPC2 HTTP/1.0" 404 3754
10.0.1.20 - - [24/May/2010:14:44:48 -0600] "POST //server1.jaxon.private//server1.jaxon.private/RPC2 HTTP/1.0" 404 3754
10.0.1.108 - - [24/May/2010:14:44:47 -0600] "PROPFIND /principals/wikis/test/ HTTP/1.1" 500 201
So there are a couple 404 not founds and a 500 Internal Sever error.
I also get entries in the site error log:
[Mon May 24 14:43:04 2010] [error] [client 10.0.1.108] File does not exist: /Library/WebServer/Documents/collaboration-availability, referer: https://server1.jaxon.private/groups/
[Mon May 24 14:44:48 2010] [error] [client 10.0.1.20] File does not exist: /Library/WebServer/Documents/server1.jaxon.private
[Mon May 24 14:44:48 2010] [error] [client 10.0.1.20] File does not exist: /Library/WebServer/Documents/server1.jaxon.private
Some additional info about our configuration is below
To start here is the output from changeip -checkhostname
Primary address = 10.0.1.20
Current HostName = server1.jaxon.private
DNS HostName = server1.jaxon.private
The names match. There is nothing to change.
dirserv:success = "success"
Under the iCal server section I have the Wiki Server listed as server1.jaxon.private with the SSL checkbox checked. Under Authentication I have type set to Any, Host Name as server1.jaxon.private, Port 8008, SSL set to Use, and SSL Port set to 8443.
Under the Web server section I have 1 site enabled with a Host Name of server1.jaxon.private, IP Address of 10.0.1.20, and Port of 443. The Options, Realms, and Logging tabs all have the default values. Under security I have the SSL certificate configured. Under Aliases and Proxy are just the defaults, and Web Services has Wikis, Calendars, and change their password options.
Any help would be appreciated.

Apple has a command line equivalent to the Server Admin GUI application that conveniently enough is called serveradmin. If you open terminal on your machine and type:
man serveradmin
You'll get the manual page for the serveradmin command. This will run you through all the different arguments you can use with the command and has some examples of the command usage.
If you type:
sudo serveradmin settings calendar
The sudo means super user do. This will temporarily escalate your privileges so you can run the command. It will then ask you for your password to verify your identity. When the command runs you will see all the different settings listed for the calendar service.
To change the value of an item you would do something like the following:
sudo serveradmin settings calendar:somesetting="new value"
