Randy pointed out (below) a serious security hole that I've been
inadvertently leaving on my sites every since I started doing that
config.php-only type of password-setting that I suggested above.  If I
am viewing a group for which I have read permission I can then
(:include:) a page for which I do *not* have read permission.

Please do *not* use my suggestion for setting just $DefaultPasswords
in config.php.  It is not just that it is "not preferable" as I
thought but simply wrong.
