+# /etc/pam.d/common-account - authorization settings common to all services
+#
+# This file is included from other service-specific PAM config files,
+# and should contain a list of the authorization modules that define
+# the central access policy for use on the system.  The default is to
+# only deny service to users whose accounts are expired in /etc/shadow.
+#
+# As of pam 1.0.1-6, this file is managed by pam-auth-update by default.
+# To take advantage of this, it is recommended that you configure any
+# local modules either before or after the default block, and use
+# pam-auth-update to manage selection of other modules.  See
+# pam-auth-update(8) for details.
