PAM (Pluggable Authentication Modules: A system that allows you to identify different authentication methods by services. On older Linux systems, when a program such as "su", "login", "passwd" wanted to authenticate the user, it would have access to the required information from the file under /etc/passwd.

Records from PAM_Unix may be in different formats depending on the operating system.It can create too many problems when it breaks down.

Available Formats:

Code:
process_name(pam_unix)[pid]:
 process_name[pid]: (pam_unix)
 process_name: pam_unix(process_name):
