How does OpenLDAP do better than Tomcat? If I make repeated (failed)
login attempts against a single user, can I cause them to be
locked-out? DOS. Does OpenLDAP track the IP address(es) of the
authentication attempts? (Tomcat would have to furnish that
information via LDAP, which I don't believe it does). If it does cache
them, I can hit you from many different IP addresses. D/DOS. If it's
got a limited cache, I can game the cache by making of attempts, get
locked-out, then purge myself from your cache by hitting you with
other requests.

Tomcat does an adequate job of mitigating casual break-in attempts.
Really good protection is difficult and often still not sufficient
because the bad guys always have the advantage.
