Bug in pam_tally on Red Hat Enterprise Linux Server release 5.1 (Tikanga).

[Vasudeva R]

Thank you Tomas,

It works perfect.

My configuration file now looks like this:

auth        required      pam_env.so
auth        required      pam_tally.so onerr=fail per_user deny=3
unlock_time=60
auth        sufficient    pam_unix.so try_first_pass
auth        required      pam_deny.so

account     required      pam_tally.so
account     required      pam_unix.so
account     sufficient    pam_succeed_if.so uid < 500 quiet
account     required      pam_permit.so

password    requisite     pam_cracklib.so minlen=7 ucredit=0 lcredit=-1
dcredit=-1 ocredit=0 retry=3
password    sufficient    pam_unix.so  use_authtok md5 shadow remember=4
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

Thank you again.

Appreciate your timely reply with proper solution.

Regards,
Vasu
