#

# This file is included from other service-specific PAM config files,

# and should contain a list of the authentication modules that define

# the central authentication scheme for use on the system

# (e.g., /etc/shadow, LDAP, Kerberos, etc.). The default is to use the

# traditional Unix authentication mechanisms.
