  That is a more "correct" solution. But would that value be used
for "modern" Kerberos5 api? Probably should be, as it still is
kerberos, and 5 :-) (so I presume only the programming API/ABI
changed, but not the "protocol"), and would replace code that
apparently has only compiled by "2 or 3 peoples" in the past
15 years.
