<simpara>Permet de définir la méthode utilisée par le serveur HTTP pour

<listitem>
<simpara>Dans cette méthode, le serveur HTTP défini la variable
d'environnement <literal>REMOTE_USER</literal>. Cette variable ne contient
que l'identifiant de l'utilisateur connecté. Cette méthode ne peut donc
être utilisée que conjointement avec l'activation du paramètre
<literal>LSAUTHMETHOD_HTTP_TRUST_WITHOUT_PASSWORD_CHALLENGE</literal>.

<term>AUTHORIZATION</term>
<listitem>
<simpara>Dans cette méthode, le serveur HTTP passe le contenu de l'entête
HTTP <literal>Authorization</literal> dans la variable d'environnement
<literal>HTTP_AUTHORIZATION</literal>. Cette méthode convient en cas d'
utilisation de PHP en mode CGI ou encore via PHP-FPM. Pour utiliser cette
méthode, il faudra adapter la configuration du serveur HTTP. Par exemple,
pour Apache HTTPd, vous pouvez utiliser le module <literal>rewrite</literal>
et la règle de réécriture suivante :
<programlisting linenumbering="unnumbered">
<![CDATA[RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]]]>

* Set the HTTP server's method to pass authentifcated user/password informations
* to PHP :
* - PHP_PASS : server define the PHP_AUTH_USER and PHP_AUTH_PW environnement
* variables. This is the default way using mod_php.
* - REMOTE_USER : server define the REMOTE_USER environnement variable. By using
* this method, only the user is pass by HTTP server to PHP and it
* could be only used if you enable the "don't check HTTP server's
* login/password by LDAP authentication challenge" option.
* - AUTHORIZATION : server pass HTTP Authorization header value to PHP by setting
* the HTTP_AUTHORIZATION environnement variable. This way could
* be use when using PHP in CGI-mode or with PHP-FPM. When using
* Apache, you could pass this information by using the rewrite module
* and setting the following rewrite rule :
* RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
