-    # The default Debian nagios4 install sets use_authentication=0 in

-    # The <Files>...</Files> below shows how you can secure the nagios4
-    # web site so anybody can view it, but only authenticated users can issue
-    # commands (such as silence notifications).  To do that replace the

-    # program from the apache2-utils package to add users to
-    # /etc/nagios4/htdigest.users.
-    #
-    # A step up is to insist all users validate themselves by moving
-    # the stanza's in the <Files>..<Files> into the <DirectoryMatch>.
-    # Then by setting use_authentication=1 in /etc/nagios4/cgi.cfg you
-    # can configure which people get to see a particular service from
