Slow password re-entry prompt after incorrect sudo password

[glasscheetah]

When an incorrect password is entered in the sudo prompt it takes a very long time for sudo to allow password re-entry.

Example:

m:~$ sudo su

Sorry, try again.

How long are we talking here? 2 or 3 seconds, or longer? Sometimes PAM is configured to delay to slow brute force attacks, but I don't think many care.

Hi, it takes 7 seconds on my machine. I find it slightly too long. Is there anyway to change it?

[Justin Dugger (jldugger)]

Have a look at the directory /etc/pam.d/ and see if there's anything that might cause a delay. PolicyKit might also play a role in the delay, or thinkfinger itself, I can't say for sure.
