auth.user.delay-length-seconds

Set the delay applied to subsequent authentication attempts after the criteria in auth.user.allowed-failures-period-length-seconds and auth.user.allowed-failures-per-period is exceeded. The delay should be a high enough value to make brute force password guessing impractical while not inconveniencing legitimate users.

Please be aware that a web server thread will be kept waiting during the delay in the current implementation, so imposing a long delay risks exhausting all web server threads.

Apply no delay to authentication attempts if many login failures are detected.

Apply a 5 second delay to authentication attempts if many login failures are detected.
