Is there any reason this:

     % kadmin -q "getprinc jblaine"
     Authenticating as principal jblaine/admin at RCF.FOO.COM with
     password.
     kadmin: Client not found in Kerberos database while initializing
     kadmin interface
     %

     (What's a "Client"?  What is it talking about?  Where is my
     (error to fix?  I don't even know based on that.)

Can't be this?

     % kadmin -q "getprinc jblaine"
     Authenticating as principal jblaine/admin at RCF.FOO.COM with
     password.
     kadmin: jblaine/admin at RCF.FOO.COM not found in Kerberos
     database while initializing kadmin interface
