--------------------------------------------

             Summary: The delay used in PasswordPolicy should not be implemented as a Thread.sleep(delay)
                 Key: DIRSERVER-1825
                 URL: https://issues.apache.org/jira/browse/DIRSERVER-1825
             Project: Directory ApacheDS
          Issue Type: Bug
    Affects Versions: 2.0.0-M11
            Reporter: Emmanuel Lecharny
             Fix For: 2.0.0-RC1


When a delay is introduced after a bind failure, we currently do a Thread.sleep() in the server
on the session that was trying to bind. This is absolutely wrong, as it may block the whole
server after a few attempt from  few users (as we use only a limited number of threads).

We should instead forbid any attempt during the delay (that means even a successful bind should
fail), as the idea behind this delay is to forbid an attack where someone submit as many bind
as possible, until one is successful.
