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.
