+<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 "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 ...

+ 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

+
+ <dt>Support for mod_authn_socache</dt>
+ <dd>mod_authn_socache interaction should be implemented for

+ 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>

+<h3>Sommaire</h3>
+
+ <p>Ce module permet aux applications d'autorisation FastCGI
+ d'authentifier les utilisateurs et de contrôler leur accès aux
+ ressources. Il supporte les systèmes d'autorisation FastCGI
+ génériques qui participent en une seule phase à l'authentification
+ et à l'autorisation, ainsi que les processus d'authentification et
+ d'autorisation spécifiques à Apache httpd qui interviennent en une
+ ou plusieurs phases.</p>
+
+ <p>Les processus d'autorisation FastCGI peuvent authentifier un
+ utilisateur via son identificateur et son mot de passe comme dans le
+ processus d'authentification basique, ou via un mécanisme
+ arbitraire.</p>

+<h2><a name="invocations" id="invocations">Modes d'invocation</a></h2>
+
+ <p>Les modes d'invocation des processus d'autorisation FastCGI que
+ ce module supporte se distinguent par deux caractéristiques : le
+ <em>type</em> et le <em>mécanisme</em> d'authentification.</p>
+
+ <p>Le <em>Type</em> est simplement <code>authn</code> pour
+ l'authentification, <code>authz</code> pour l'autorisation et
+ <code>authnz</code> l'authentification et l'autorisation.</p>
+
+ <p>Le <em>mécanisme</em> d'authentification fait référence aux
+ mécanismes d'authentification et aux phases de traitement de la
+ configuration de Apache httpd, et peut être
+ <code>AuthBasicProvider</code>, <code>Require</code>, ou
+ <code>check_user_id</code>. Les deux premiers mécanismes
+ correspondent aux directives utilisées pour participer aux phases de
+ traitement appropriées.</p>
+
+ <p>Description de chaque mode:</p>
+
+ <dl>
+ <dt><em>Type</em> <code>authn</code>, <em>mechanism</em>
+ <code>AuthBasicProvider</code></dt>
+
+ <dd>Dans ce mode, la variable <code>FCGI_ROLE</code> est définie à
+ <code>AUTHORIZER</code>, et la variable
+ <code>FCGI_APACHE_ROLE</code> à <code>AUTHENTICATOR</code>.
+ L'application doit être spécifiée en tant que fournisseur de type
+ <em>authn</em> via la directive <code class="directive"><a href="#authnzfcgidefineprovider">AuthnzFcgiDefineProvider</a></code>, et
+ activée via la directive <code class="directive"><a href="../mod/mod_auth_basic.html#authbasicprovider">AuthBasicProvider</a></code>. Lorsqu'elle
+ est invoquée, l'application est censée authentifier le client à
+ l'aide de l'identifiant et du mot de passe de l'utilisateur.
+ Exemple d'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>
+
+
+ Exemple de configuration httpd :
+<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>Dans ce mode, la variable <code>FCGI_ROLE</code> est définie à
+ <code>AUTHORIZER</code> et <code>FCGI_APACHE_ROLE</code> à
+ <code>AUTHORIZER</code>. L'application doit être spécifiée en tant
+ que fournisseur de type <em>authz</em> via la directive <code class="directive"><a href="#authnzfcgidefineprovider">AuthnzFcgiDefineProvider</a></code>.
+ Lorsqu'elle est invoquée, l'application est censée contrôler les
+ accès du client à l'aide de l'identifiant utilisateur et d'autres
+ données contenues dans la requête. Exemple d'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 "Status: 200\n";
+ print "Variable-AUTHZ_1: authz_01\n";
+ print "Variable-AUTHZ_2: authz_02\n";
+ print "\n";
+ }
+ else {
+ print "Status: 403\n\n";
+ }
+}</pre>
+
+
+ Exemple de configuration httpd :
+<pre class="prettyprint lang-config">AuthnzFcgiDefineProvider authz FooAuthz fcgi://localhost:10103/
+&lt;Location "/protected/"&gt;
+ AuthType ...
+ AuthName ...
+ AuthBasicProvider ...
+ 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>Dans ce mode qui supporte le protocole d'autorisation web
+ server-agnostic FastCGI, la variable <code>FCGI_ROLE</code> est
+ définie à <code>AUTHORIZER</code> et <code>FCGI_APACHE_ROLE</code>
+ n'est pas définie. L'application doit être spécifiée en tant que
+ fournisseur de type <em>authnz</em> via la directive <code class="directive"><a href="#authnzfcgidefineprovider">AuthnzFcgiDefineProvider</a></code>.
+ L'application est censée assurer l'authentification et
+ l'autorisation au cours d'une même invocation à l'aide de
+ l'identifiant et du mot de passe de l'utilisateur et d'autres
+ données contenues dans la requête. L'invocation de l'application
+ intervient au cours de la phase d'authentification de l'API Apache
+ httpd. Si l'application renvoie le code 200, et si le même
+ fournisseur est invoqué au cours de la phase d'autorisation (via
+ une directive <code class="directive">Require</code>), mod_authnz_fcgi
+ renverra un code de type success pour la phase d'autorisation sans
+ invoquer l'application. Exemple d'application :
+<pre class="prettyprint lang-perl">#!/usr/bin/perl
+use FCGI;
+my $request = FCGI::Request();
+while ($request-&gt;Accept() &gt;= 0) {

+
+ 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" &amp;&amp;
+ $ENV{'REQUEST_URI'} =~ m%/bar/.*%) {
+ print "Status: 200\n";
+ print "Variable-AUTHNZ_1: authnz_01\n";

+ <dd>La phase <em>access check</em> de l'API Apache httpd est

+ Certaines autres implémentations de FastCGI supportent cette phase
+ et lorsque c'est le cas, la variable <code>FCGI_APACHE_ROLE</code>

+
+ <dt>Redirections (pipes) ou sockets locaux (Unix)</dt>
+ <dd>Seuls les sockets TCP sont actuellement supportés.</dd>
+
+ <dt>Support de mod_authn_socache</dt>
+ <dd>Le support de l'interaction avec mod_authn_socache pour les

+
+ <dt>Support de l'authentification de type digest à l'aide de AuthDigestProvider</dt>
+ <dd>Cette limitation ne sera probablement jamais franchie car il

+ un condensé de type hash.</dd>
+
+ <dt>Gestion des processus applicatifs</dt>
+ <dd>Cette fonctionnalité restera probablement hors de portée de ce
+ module. Il faudra donc gérer les processus applicatifs d'une autre
+ manière ; par exemple, <code class="program"><a href="../programs/fcgistarter.html">fcgistarter</a></code> permet de
+ les démarrer.</dd>
+
+ <dt>AP_AUTH_INTERNAL_PER_URI</dt>
+ <dd>Tous les fournisseurs sont actuellement enregistrés en tant
+ que AP_AUTH_INTERNAL_PER_CONF, ce qui signifie que les
+ vérifications ne sont pas effectuées pour les
+ sous-requêtes internes avec la même configuration de contrôle
+ d'accès que la requête initiale.</dd>
+
+ <dt>Conversion du jeu de caractères des données de protocole</dt>
+ <dd>Si mod_authnz_fcgi s'exécute dans un environnement de

+ écrites en EBCDIC et doivent être disponibles en EBCDIC.</dd>
+
+ <dt>Plusieurs requêtes pour une connexion</dt>
+ <dd>Actuellement, la connexion au fournisseur d'autorisation
+ FastCGI est fermée après chaque phase de traitement. Par exemple,

+ <p>Cette directive permet de confier à une application FastCGI la
+ gestion d'une phase spécifique du processus d'authentification ou
+ d'autorisation.</p>
+
+ <p>Certaines fonctionnalités des fournisseurs d'autorisation FastCGI
+ nécessitent cette directive en lieu et place de
+ <code class="directive">AuthBasicProvider</code> pour pouvoir être activées :</p>
+
+ <ul>
+ <li>L'authentification de type autre que basique ; en général,
+ détermination de l'identifiant utilisateur et renvoi de sa valeur
+ depuis le fournisseur d'autorisation ; voir l'option
+ <code>UserExpr</code> ci-dessous</li>
+ <li>Sélection d'un code de réponse personnalisé ; en cas de
+ code de réponse autre que 200 en provenance du fournisseur
+ d'autorisation, c'est ce code qui sera utilisé comme code d'état
+ de la réponse</li>
+ <li>Définition du corps d'une réponse autre que 200 ; si le
+ fournisseur d'autorisation renvoie un corps de réponse avec un
+ code autre que 200, c'est ce corps de réponse qui sera renvoyé au
+ client ; la longueur du texte est limitée à 8192 octets</li>
+ </ul>
+
+ <dl>
+ <dt><em>provider-name</em></dt>
+ <dd>C'est le nom du fournisseur défini au préalable via la
+ directive <code class="directive">AuthnzFcgiDefineProvider</code>.</dd>
+
+ <dt><code>None</code></dt>
+ <dd>Spécifiez <code>None</code> pour désactiver un fournisseur
+ activé avec cette même directive dans une autre portée, par
+ exemple dans un répertoire parent.</dd>
+
+ <dt><em>option</em></dt>
+ <dd>Les options suivantes sont supportées :
+
+ <dl>
+ <dt>Authoritative On|Off (par défaut On)</dt>
+ <dd>Cette option permet de définir si l'appel à d'autres
+ modules est autorisé lorsqu'un fournisseur d'autorisation FastCGI a
+ été configuré et si la requête échoue.</dd>
+
+ <dt>DefaultUser <em>id utilisateur</em></dt>
+ <dd>Lorsque le fournisseur d'autorisation donne son accord, et
+ si <code>UserExpr</code> est défini et correspond à une chaîne
+ vide, (par exemple, si le fournisseur d'autorisation ne renvoie
+ aucune variable), c'est cette valeur qui sera utilisée comme id
+ utilisateur par défaut. Cela se produit souvent lorsqu'on se trouve dans
+ un contexte d'invité, ou d'utilisateur non authentifié ;
+ les utilisateurs et invités se voient alors attribué un id
+ utilisateur spécifique qui permettra de se connecter et
+ d'accéder à certaines ressources.</dd>
+
+ <dt>RequireBasicAuth On|Off (par défaut Off)</dt>
+ <dd>Cette option permet de définir si l'authentification
+ basique est requise avant de transmettre la requête au
+ fournisseur d'autorisation. Dans l'affirmative, le fournisseur
+ d'autorisation ne sera invoqué qu'en présence d'un id
+ utilisateur et d'un mot de passe ; si ces deux éléments ne sont
+ pas présents, un code d'erreur 401 sera renvoyé</dd>
+
+ <dt>UserExpr <em>expr</em> (pas de valeur par défaut)</dt>
+ <dd>Lorsque le client ne fournit pas l'authentification basique
+ et si le fournisseur d'autorisation détermine l'id utilisateur,
+ cette expression, évaluée après l'appel au fournisseur
+ d'autorisation, permet de déterminer l'id utilisateur. Cette
+ expression se conforme à la <a href="../expr.html">syntaxe
+ ap_expr</a> et doit correspondre à une chaîne de caractères.
+ Une utilisation courante consiste à référencer la définition
+ d'une <code>Variable-<em>XXX</em></code> renvoyée par le
+ fournisseur d'autorisation via une option du style
+ <code>UserExpr "%{reqenv:<em>XXX</em>}"</code>. Si cette option
+ est spécifiée, et si l'id utilisateur ne peut pas être définie
+ via l'expression après une authentification réussie, la requête
+ sera rejetée avec un code d'erreur 500.</dd>
