Hmmm.... Now I'm confused again. Maybe my mental model is screwed up. I
was assuming that the host principles listed in the keytab on the
destination system were being used to verify the identity of the
incoming client host, sort of like ssh's known_hosts? But then, how does
the incoming system choose it's principle identity?

Keytab name: FILE:/etc/krb5.keytab
KVNO Principal
