Hi,
May I ask a quick question? Is there any rate-limited mechanism in KDC? I
am asking for two reasons. First, if there is a DoS attack, I think KDC
needs to have some kind of rate-limiting to eliminate the attack. Am I
right? Secondly, for performance banch marking, if there is a rate-limiting
in place, that will be an upper bound for the performance for instance in
terms of ticket throughput?

Thank you!
Yegui C
