The attached patch is a contrib module to inject a few seconds
delay on authentication failed. It is also a proof of the concept
using the new ClientAuthentication_hook.
This module provides a similar feature to pam_faildelay on
operating systems. Injection of a few seconds delay on
authentication fails prevents (or makes hard at least) brute-force
attacks, because it limits number of candidates that attacker can
verify within a unit of time.
Thanks,
