+# /etc/pam.d/common-password - password-related modules common to all services
+#
+# This file is included from other service-specific PAM config files,
+# and should contain a list of modules that define the services to be
+# used to change user passwords.  The default is pam_unix.
+
+# Explanation of pam_unix options:
+#
+# The "sha512" option enables salted SHA512 passwords.  Without this option,
+# the default is Unix crypt.  Prior releases used the option "md5".
+#
+# The "obscure" option replaces the old `OBSCURE_CHECKS_ENAB' option in
+# login.defs.
+#
+# See the pam_unix manpage for other options.
+
+# here are the per-package modules (the "Primary" block)
+password        [success=2 default=ignore]      pam_unix.so obscure sha512
+password        [success=1 default=ignore]      pam_ldap.so minimum_uid=1000 try_first_pass
+# here's the fallback if no module succeeds
+password        requisite                       pam_deny.so
+# prime the stack with a positive return value if there isn't one already;
+# this avoids us returning an error just because nothing sets a success code
+# since the modules above will each just jump around
+password        required                        pam_permit.so
+# and here are more per-package modules (the "Additional" block)
+# end of pam-auth-update config
