pam_tally: unknown option

["Monu Agrawal" <monuindia gmail com>]

Hi,
I am using pam-0.77-65.1. The problem I am getting with it is, I am not able to set deny and unlock_time options.
My file looks like following:
#%PAM-1.0
auth       required     pam_stack.so service=system-auth
auth       required     pam_nologin.so
auth       required     pam_tally.so deny=3  unlock_time=600
account    required     pam_tally.so
account    required     pam_stack.so service=system-auth
password   required     pam_stack.so service=system-auth
session    required     pam_stack.so service=system-auth

I am getting the following error messages on /var/log/messages

Jun 16 17:05:32 ssc-216 pam_tally[26272]: pam_tally: unknown option; deny=3
Jun 16 17:05:32 ssc-216 pam_tally[26272]: pam_tally: unknown option; unlock_time=600

Are these options available on the this particular version? Can anybody tell me what is wrong with the above config?
