 #  An example configuration for using /etc/passwd.
 #
-#  We do NOT recommend using the configuration below.  See the "unix"
-#  module, or the "pam" module for a cleaner way to get system passwords.
-#  Using this configuration means that the server will find *only* those
-#  passwords which are in /etc/passwd, and will *ignore* all of the
-#  passwords in NIS, LDAP, etc.
+#  This is an example which will NOT WORK if you have shadow passwords,
+#  NIS, etc.  The "unix" module is normally responsible for reading
+#  system passwords.  You should use it instead of this example.
