Problem with a Stuck ML Calendar Client using Server Calendar

Question

I set up group Wikis on our server, which seem to work fine (as long as everyone remembers to log in with "https:" not "http:".
On my ML client however, after cleaning out old Calendar accounts with the server, using System Preferences to create a Calendar account with the server, and then reopening Calendar, I can see the Server as a calendar source on the left pane but always get a message that says:
"The URL https://<server URL>/principals/__uids__/0D06B83A-D825-4318-816C-097904CB4886/ encountered HTTP error 404. Make sure the URL is correct."
I suspect that the hex code for my user ID is wrong (or maybe it is a group ID). But I can't seem to fix this. There is no place in the application to edit this URL. I can delete the server account from Calendar and try to start again and I still get the same message.
Is there a configuration file where I can kill this and start over? I suspect some of my other clients to the server will also have this problem as I migrate them over.
Thanks!

Answer 1

I am still trying to debug this problem.
I have tried removing the Server account from Calendar Preferences as well as System Preferences, then readding. Did not work.
I tried doing the remove again, this time removing everything in Keychain associated with the Server Calendars. Did not work.
I tried going to ../<User>/Library/Calendars and navigating to the caldav directory associated with the server (this takes some poking around as the directory name is based on the server's hex identifier), then renaming the Info.plist file, then deleting the account from System Preferences, then recreating. Did not work. In fact the renamed Info.plist file was gone, but a new one was there.
The Info.plist file contained the bad entry in several places. This is what mine looks like (with specific servers and user names replaced):

This tells me that my client is pulling this information down from the server. Annoying. Where is the configuration file on Mountain Lion Server? Why does it use the Hex address??? Short name would be infinitely better!
