howto increase delays in password prompt

["Mutsuura Associates, Inc." <mutsuura@mutsuura.com>]

HI All

A quick question...

I recently did a 'standard' netinstall version of Sarge. I've been playing with 
/etc/login.defs, UNsuccessfully, trying to increase the delay for password 
prompts from the current '3' second default if/when the wrong password is 
entered during login.

I tried changing the FAIL_DELAY as denoted below:

<...snip...>
#
# Delay in seconds before being allowed another attempt after a login failure
#
FAIL_DELAY              30
<...snip...>

...however when I intentionally supply the wrong password, it STILL prompts for 
new password '3' seconds later! I believe PAM is running but there's nothing in 
the background that would indicate that:

<...snip...>
userxx@hostname:/$ ps -Af | grep -i pam
root       973     1  0 Mar10 ?        00:00:00 /usr/sbin/spamd --create-prefs 
--max-children 5 --helper-home-dir -d --pidfile=/var/run/spamd.pid
root      1047   973  0 Mar10 ?        00:00:00 spamd child
root      1048   973  0 Mar10 ?        00:00:00 spamd child
root      1049   973  0 Mar10 ?        00:00:00 spamd child
root      1052   973  0 Mar10 ?        00:00:00 spamd child
root      1057   973  0 Mar10 ?        00:00:00 spamd child
userxx   25455 25283  0 11:05 pts/4    00:00:00 grep -i pam
<...snip...>

Can anyone tell me how to increase the delay properly?

Much thx to the group,
