ICal Server - Can't log in with Kerberos?

Question

Hello, I have been struggling the past few days getting ical server properly installed and configured to incorporate into our environment (just installed 10.6 server). I am very new to Kerberos, in fact never heard of it before getting into this, but would like to possibly use it as an authentication option. I have my master open directory installed and running, it says Kerberos is running, ldap as well as password server, all running. I created some test users in the LDAPv3/127.0.0.1 directory with open directory password types. I have opened ticket viewer and assigned tickets to these test users. In my Ical settings in server admin, I have authentication type set to kerberos. When I try to add an account via my ical client on my workstation (also 10.6 just installed), it searches and I get the message:
"Ical found the CALDAV server "servername" but couldn't log in with the user name "username". Make sure the user name and password you entered are correct, then try again"
If I click next and go to the calendar server options screen I select Ical server template, the port changes to 8443 I believe and I change it back to the default of 8008, and click use kerberos v5 for authentication, and uncheck Use SSL as I have that off. I then get the message of:
"Authentication failed. The server does not support Kerberos authentication."
Now, if I go completely backward, and change my iCal server authentication type to Digest, or Any Method, I can log in using any of my local user names and passwords and any open directory password users. This is great because it shows me the system is working, and I can get in, however what I don't quite understand is if I log in with a different/various usernames and passwords, I get a separate calendar for each login. When watching the apple demo video of Ical server here http://www.youtube.com/watch?v=7bzMTpLv-EE&feature=related , it seems there is one calendar, and multiple users are logging in using different logins, but accessing the same calendar.
So I guess my main questions are, why isn't Kerberos working, and how do I get it to work, am I missing something? And how do I get Ical server to operate the way it is in the video, so people log in with different various logins but are able to see the same "work" calendar as shown in the video.
I appreciate any help/insight. Thank you.

One additional piece of information that I don't know if it is a bug or if anyone else has this problem, but when I am logged in with a user, and access my address panel via my ical client, none of my locations, resources, people, or groups show up, every category is empty. However, if I start to type a search for a location name or user that I know the name of that I have added, THEN it will show up and I can click/select it. Almost behaving completely backwards, any ideas why these are not showing up without using the search??? Thank you again.
