I am trying to use mod_ruby's RubyAuthzHandler directive under Apache
2.0.52on Linux.  The Ruby object referenced by this directive seems to
never get
invoked, although RubyAccessHandler and RubyAuthenHandler work great.

Below is the httpd.conf (excerpt) and Ruby class I'm trying to make work.
This is supposed to successfully pass the Access and Authentication stages,
and yield a Forbidden error in the Authorization stage.  Instead, the
request goes through successfully.  If I edit the Ruby file and change the
authenticate() method to return Apache::FORBIDDEN, the request does
correctly get forbidden.

The strange thing is, even if I completely comment-out the authorize()
method, no error occurs anywhere.  If I did that for authenticate(), I get
"undefined method `authenticate'" in the server error log.  It's as though
RubyAuthzHandler is unimplemented, but it does seem to be in the mod_ruby
source code.

Has anyone out there successfully used RubyAuthzHandler?  Am I doing
something wrong?  Thanks for any advice!

    <IfModule mod_ruby.c>
      <Files *.html>
      RubyAddPath /path/to/myauth
      RubyRequire myauth
      require valid-user

      RubyAccessHandler MyAuth.instance
      RubyAuthenHandler MyAuth.instance
      RubyAuthzHandler MyAuth.instance
      </Files>
    </IfModule>

require 'singleton'
class MyAuth
      include Singleton

      #function called via RubyAccessHandler
      def check_access(req)
            return Apache::OK
      end

     #function called via RubyAuthenHandler
      def authenticate(req)
            return Apache::OK
      end

     #function called via RubyAuthzHandler
      def authorize(req)
            return Apache::FORBIDDEN
      end
end
