8.6. Pluggable Authentication Modules (PAM)
8.6. Pluggable Authentication Modules (PAM) Common configuration for PAM services is located in the /etc/pam.d/system-auth-ac file. Authentication modules are now also written into additional PAM configuration files: /etc/pam.d/password-auth-ac , /etc/pam.d/smartcard-auth-ac and /etc/pam.d/fingerprint-auth-ac . The PAM module for sshd and other remote services such as ftpd now include the /etc/pam.d/password-auth file in Red Hat Enterprise Linux 6 instead of /etc/pam.d/system-auth .
