Sounds interesting. I guess re-measuring the Heimdal+OpenLDAP numbers
now would give better values, there's been suggestions on how to
improve the performace too, but I'm afraid I don't know enough of LDAP
to remember how. :-)

I think it's all there; kadmin/add_random_users creates a bunch of
"random" users, and kuser/generate_requests sends requests to the KDC
based on a set of usernames. Since the kadmin API is not very
standard, you will likely have to modify the former, but the latter
should work with any KDC.
