             Mod_Auth_Remote - remote authentication module for apache 2.2

  mod_auth_remote is as an authentication provider. mod_auth_remote is configured with an
  authentication server url. The authentication server url is an application usually hosted
  by another webserver or webservice which is responsible for the actual authentication of
  users.

  mod_auth_remote accepts HTTP BASIC authentication requests and proxies a HTTP BASIC 
  Auth 'HEAD' request to the authentication server url on the local requests behalf.
  The authentication server may allow or decline authentication based on it's policy. If the 
  response from the authentication server is a SUCCESS code (2XX), mod_auth_remote will grant 
  AUTHENTICATION on the local server. For all other responses mod_auth_remote will deny local 
  AUTHENTICATION.


  Using mod_auth_remote gives you the following advantages

  * Simple way to implement Single-Signon. Same set of credentials can be used by 
    many applications/webservers.

  * No need to replicate your authentication framework to all your applications
      -- No need to punch holes through your firewall for sql access or ldap access as part of 
         your authentication setup.
      -- Authentication server need not be publicly accessible to actual clients
      -- Tweak your authentication mechanism and ACLs without touching the fronting webservers

  * A single webserver can have different URLs/applications authenticating from many 
    different authentication servers without duplicating any of their configuration or code.

  * If you use mod_auth_remote's AuthRemoteCookie support you can decrease load on the 
    authenticating servers drastically, as only 1 backend authentication per session is required.

  This is a complete rewrite of mod_auth_remote specifically for apache 2.2 (& apr 1.3). 
  I intend to add new functionality only to this version for now.
