+<h3>Summary</h3>
+
+ <p>This module allows FastCGI authorizer applications to
+ authenticate users and authorize access to resources. It supports
+ generic FastCGI authorizers which participate in a single phase
+ for authentication and authorization as well as Apache httpd-specific
+ authenticators and authorizors which participate in one or both
+ phases.</p>
+
+ <p>FastCGI authorizers can authenticate using user id and password,
+ such as for Basic authentication, or can authenticate using arbitrary
+ mechanisms.</p>

+<h2><a name="invocations" id="invocations">Invocation modes</a></h2>
+
+ <p>The invocation modes for FastCGI authorizers supported by this
+ module are distinguished by two characteristics, <em>type</em> and
+ auth <em>mechanism</em>.</p>
+
+ <p><em>Type</em> is simply <code>authn</code> for authentication,
+ <code>authz</code> for authorization, or <code>authnz</code> for
+ combined authentication and authorization.</p>
+
+ <p>Auth <em>mechanism</em> refers to the Apache httpd configuration
+ mechanisms and processing phases, and can be <code>
+ AuthBasicProvider</code>, <code>Require</code>, or <code>
+ check_user_id</code>. The first two of these
+ correspond to the directives used to enable participation in the
+ appropriate processing phase.</p>
+
+ <p>Descriptions of each mode:</p>
+
+ <dl>
+ <dt><em>Type</em> <code>authn</code>, <em>mechanism</em>
+ <code>AuthBasicProvider</code></dt>
+
+ <dd>In this mode,
+ <code>FCGI_ROLE</code> is set to <code>AUTHORIZER</code> and
+ <code>FCGI_APACHE_ROLE</code> is set to <code>AUTHENTICATOR</code>.
+ The application must be defined as provider type <em>authn</em>
+ using <code class="directive"><a href="#authnzfcgidefineprovider">
+ AuthnzFcgiDefineProvider</a></code> and enabled with
+ <code class="directive"><a href="../mod/mod_auth_basic.html#authbasicprovider">AuthBasicProvider</a></code>.
+ When invoked, the application is
+ expected to authenticate the client using the provided user id and
+ password. Example application:
+
+<pre class="prettyprint lang-perl">#!/usr/bin/perl
+use FCGI;
+my $request = FCGI::Request();
+while ($request-&gt;Accept() &gt;= 0) {
+ die if $ENV{'FCGI_APACHE_ROLE'} ne "AUTHENTICATOR";
+ die if $ENV{'FCGI_ROLE'} ne "AUTHORIZER";
+ die if !$ENV{'REMOTE_PASSWD'};
+ die if !$ENV{'REMOTE_USER'};
+
+ print STDERR "This text is written to the web server error log.\n";
+
+ if ( ($ENV{'REMOTE_USER' } eq "foo" || $ENV{'REMOTE_USER'} eq "foo1") &amp;&amp;
+ $ENV{'REMOTE_PASSWD'} eq "bar" ) {
+ print "Status: 200\n";
+ print "Variable-AUTHN_1: authn_01\n";
+ print "Variable-AUTHN_2: authn_02\n";
+ print "\n";
+ }
+ else {
+ print "Status: 401\n\n";
+ }
+}</pre>
+
+
+ Example configuration:
+<pre class="prettyprint lang-config">AuthnzFcgiDefineProvider authn FooAuthn fcgi://localhost:10102/
+&lt;Location "/protected/"&gt;
+ AuthType Basic
+ AuthName "Restricted"
+ AuthBasicProvider FooAuthn
+ Require ...
+&lt;/Location&gt;</pre>
+
+ </dd>
+
+ <dt><em>Type</em> <code>authz</code>, <em>mechanism</em>
+ <code>Require</code></dt>
+ <dd>In this mode, <code>FCGI_ROLE</code> is set to <code>
+ AUTHORIZER</code> and <code>FCGI_APACHE_ROLE</code> is set to
+ <code>AUTHORIZER</code>. The application must be defined as
+ provider type <em>authz</em> using <code class="directive"><a href="#authnzfcgidefineprovider">
+ AuthnzFcgiDefineProvider</a></code>. When invoked, the application
+ is expected to authorize the client using the provided user id and other
+ request data. Example application:
+<pre class="prettyprint lang-perl">#!/usr/bin/perl
+use FCGI;
+my $request = FCGI::Request();
+while ($request-&gt;Accept() &gt;= 0) {
+ die if $ENV{'FCGI_APACHE_ROLE'} ne "AUTHORIZER";
+ die if $ENV{'FCGI_ROLE'} ne "AUTHORIZER";
+ die if $ENV{'REMOTE_PASSWD'};
+
+ print STDERR "This text is written to the web server error log.\n";
+
+ if ($ENV{'REMOTE_USER'} eq "foo1") {

+ print "Variable-AUTHZ_2: authz_02\n";
+ print "\n";
+ }
+ else {
+ print "Status: 403\n\n";
+ }
+}</pre>
+
+
+ Example configuration:
+<pre class="prettyprint lang-config">AuthnzFcgiDefineProvider authz FooAuthz fcgi://localhost:10103/
+&lt;Location "/protected/"&gt;
+ AuthType ...
+ AuthName ...

+ Require FooAuthz
+&lt;/Location&gt;</pre>
+
+ </dd>
+
+ <dt><em>Type</em> <code>authnz</code>, <em>mechanism</em>
+ <code>AuthBasicProvider</code> <em>+</em> <code>Require</code></dt>
+
+ <dd>In this mode, which supports the web server-agnostic FastCGI
+ <code>AUTHORIZER</code> protocol, <code>FCGI_ROLE</code> is set to
+ <code>AUTHORIZER</code> and <code>FCGI_APACHE_ROLE</code> is not set.
+ The application must be defined as provider type <em>authnz</em>
+ using <code class="directive"><a href="#authnzfcgidefineprovider">
+ AuthnzFcgiDefineProvider</a></code>. The application is expected to
+ handle both authentication and authorization in the same invocation
+ using the user id, password, and other request data. The invocation
+ occurs during the Apache httpd API authentication phase. If the
+ application returns 200 and the same provider is invoked during the
+ authorization phase (via <code class="directive">Require</code>), mod_authnz_fcgi
+ will return success for the authorization phase without invoking the
+ application. Example application:
+<pre class="prettyprint lang-perl">#!/usr/bin/perl
+use FCGI;
+my $request = FCGI::Request();
+while ($request-&gt;Accept() &gt;= 0) {
+ die if $ENV{'FCGI_APACHE_ROLE'};

+ <dd>The Apache httpd API <em>access check</em> phase is a separate

+ <dd>Only TCP sockets are currently supported.</dd>
+
+ <dt>Support for mod_authn_socache</dt>
+ <dd>mod_authn_socache interaction should be implemented for
+ applications which participate in Apache httpd-style
+ authentication.</dd>
+
+ <dt>Support for digest authentication using AuthDigestProvider</dt>
+ <dd>This is expected to be a permanent limitation as there is
+ no authorizer flow for retrieving a hash.</dd>
+
+ <dt>Application process management</dt>
+ <dd>This is expected to be permanently out of scope for
+ this module. Application processes must be controlled by
+ other means. For example, <code class="program"><a href="../programs/fcgistarter.html">fcgistarter</a></code> can be used to
+ start them.</dd>
+
+ <dt>AP_AUTH_INTERNAL_PER_URI</dt>
+ <dd>All providers are currently registered as
+ AP_AUTH_INTERNAL_PER_CONF, which means that checks are not
+ performed again for internal subrequests with the same
+ access control configuration as the initial request.</dd>
+
+ <dt>Protocol data charset conversion</dt>
+ <dd>If mod_authnz_fcgi runs in an EBCDIC compilation
+ environment, all FastCGI protocol data is written in EBCDIC
+ and expected to be received in EBCDIC.</dd>
+
+ <dt>Multiple requests per connection</dt>
+ <dd>Currently the connection to the FastCGI authorizer is
+ closed after every phase of processing. For example, if the
+ authorizer handles separate <em>authn</em> and <em>authz</em>
+ phases then two connections will be used.</dd>
