Account lockout policy

Hi all;

I m using Red Hat Enterprise Linux Server release 5.1 (Tikanga) and I'm trying to setup password lockout policy so that a user account locks out after 3 failed attempts.

Here are the entires of my /etc/pam.d/system-auth

Code:
#%PAM-1.0
# This file is auto-generated.
# User changes will be destroyed the next time authconfig is run.
auth        required      pam_env.so
auth        required      pam_tally.so onerr=fail no_magic_root
auth        sufficient    pam_unix.so nullok try_first_pass
auth        requisite     pam_succeed_if.so uid >= 500 quiet
auth        required      pam_deny.so

account     required      pam_unix.so
account     required      pam_tally.so deny=3 no_magic_root reset
account     sufficient    pam_succeed_if.so uid < 500 quiet
account     required      pam_permit.so

password    requisite     pam_cracklib.so try_first_pass retry=3
password    sufficient    pam_unix.so md5 shadow nullok try_first_pass use_authtok
password    required      pam_deny.so

session     optional      pam_keyinit.so revoke
session     required      pam_limits.so
session     [success=1 default=ignore] pam_succeed_if.so service in crond quiet use_uid
session     required      pam_unix.so

I have a /var/log/faillog.

How ever when i test it by failing to authenticate a user it is not locking the user account.Is there something that I'm missing.Please advise.

Regards,
Syed

Account policy does not define user authenticate..

Try this
Code:
auth        required      pam_tally.so deny=3 unclok_time=600 even_deny_root_account
