kerberos ftpd bug? can't get it to work!

[Douglas E. Engert]

You are trying to hid your identity so well that one has troubles telling
what is your real problem. 

It looks like the host is  emssyb1.toplfo.fpl.com But I don't see this in DNS.
What is is really,and what names are really in the keytab?
