There is a bug in kadmin such that if it can not establish a connection
to the admin server to a realm the first time it tries, it will not try
again the second time and will produce a Confusing Error Message:
Example: (with /etc/krb.conf moved out of the way; this also happens if
you run a 7.3 kadmin on a 7.2 machine which doesn't have the
compatibility symlinks):
Welcome to the Kerberos Administration Program, version 2
Type "help" if you need it.
admin: cpw tytso
kadm error for realm ATHENA.MIT.EDU: Could not find administrating host
admin: cpw tytso
