Description:

This module performs no authenication task; its sole purpose is to set the pam_fail_delay. The time is specified in seconds unless units are given. Units may be us (microseconds), ms (milliseconds), s (seconds) or m (minutes). If more than one argument is given, the delay set is the sum of all the specified delays.

This module should be placed in the list of authentication modules before any modules that check passwords.
