Subject: [CentOS] pam update

Hi, I’m currently using, CentOS release 4.8 (Final) and wanted to update the pam_tally module to support  unlock_time.

I understand this is only support on centos 5.x and up. What are my options for updating pam_tally to support unlock_time, can I simply download and update from a centos repo or should I compile pam. I would appreciate some suggestions.
