passwd: Unable to set failure delay
 

hi I want to change the password of a user so I am using passwd commond , but it is throwing an error
passwd: Unable to set failure delay.
I want to implement PAM on DiskOnChip so I copied all required files ( pam and required .so) and when I want to change the password of a user it is showing me above error.
what would be the cause.

PAM adds a delay to guard against brute forcing and other mischief, the delay is added when the module your using (or a module in the stack) fails. If your module can handle the "debug" parameter, add it to the config and it should log much more to syslog. IIRC, it's best you add an entry, or at least make sure there's a
*.*<tab>/var/log/debug
line in your syslog which will log all msgs.
