Kerberos pop service principal missing for email

Now that Panther has been out for a while I am hoping somone has enough experience with it to help me with this problem. I asked this question a couple of months ago but got not response. I assume it was because no one had yet looked at this. I installed a fresh copy of Panther server and have most everything working except email. When I try to get mail from my POP server, which is set up for Kerberos authentication (I'm running Open Directory master), the mail log shows the error message: No service principal found for: pop_principal Unfortunately, I cannot get any of the kadmin tools to work so I cannot add that principal myself (although I wonder why it was not created automatically by the installer). None of the Kerberos files are in any of the expected places (or anywhere I can find either). Obviously, they exist somewhere since Kerberos authentication is working for Open Directory but not where they should be (/var/db/krb5kdc or /etc/krb5*). I am at my wits end trying to find how Kerberos was implemented under Panther so I can fix this. Can someone please help me out? TIA.
