Thanks for clarifying that. Can you further confirm or correct these
two assumptions I'm making following on from this ...
1/ Our kadmin/history key has a single-DES and and another enctype, so
we're safe for now.
2/ If we rekey the kadmin/hostory key then all previous password
history will be unavailable, so users will be able to reuse some
previously used passwords (those set when the old kadmin/history key
was in operation).
