Lorsque <abbr title="LemonLDAP::NG">LL::NG</abbr> est utilisé en mode reverse-proxy, la variable d'environnement <code>REMOTE_USER</code> n'est pas renseignée. Toutefois, cette variable est renseignée par l'agent dans le serveur physique l'hébergeant mais pas dans les autres serveurs sans agents.

Le <a href="http://httpd.apache.org/docs/current/mod/mod_setenvif.html" class="urlextern" title="http://httpd.apache.org/docs/current/mod/mod_setenvif.html" rel="nofollow">module SetEnvIf</a> d'Apache peut transformer l'en-tête HTTP Auth-User en variable d'environnement <code>REMOTE_USER</code> :
|
|
</p>
|
|
<pre class="code file apache"><span class="kw1">SetEnvIfNoCase</span> Auth-<span class="kw1">User</span> <span class="st0">"(.*)"</span> REMOTE_USER=$1</pre>
|
|
|
|
<p>
|
|
Ceci permet de protéger des applications nécessitant la variable d'environnement <code>REMOTE_USER</code> en mode reverse-proxy. Dans ce cas 2 fichiers de configuration Apache doivent être renseignés :
|
|
</p>
|
|
<ul>
|
|
<li class="level1"><div class="li"> le fichier de configuration d'Apache sur le reverse-proxy <abbr title="LemonLDAP::NG">LL::NG</abbr> (celui qui héberge l'agent <abbr title="LemonLDAP::NG">LL::NG</abbr>):</div>
|
|
</li>
|
|
</ul>
|
|
<pre class="code file apache"><<span class="kw3">VirtualHost</span> *:<span class="nu0">80</span>>
|
|
<span class="kw1">ServerName</span> application.example.com
|

PerlHeaderParserHandler Lemonldap::NG::Handler
|
|
|

<span class="kw1">ProxyPreserveHost</span> <span class="kw2">on</span>
|
|
<span class="kw1">ProxyPass</span> / http://APPLICATION_IP/
|
|
<span class="kw1">ProxyPassReverse</span> / http://APPLICATION_IP/
|
|
|
|
</<span class="kw3">VirtualHost</span>></pre>
|
|
<ul>
|
|
<li class="level1"><div class="li"> le fichier de configuration d'Apache sur le serveur d'application (celui qui héberge l'application):</div>
|
|
</li>
|
|
</ul>
|
|
<pre class="code file apache"><<span class="kw3">VirtualHost</span> *:<span class="nu0">80</span>>
|
|
<span class="kw1">ServerName</span> application.example.com
|
|
|
|
<span class="kw1">SetEnvIfNoCase</span> Auth-<span class="kw1">User</span> <span class="st0">"(.*)"</span> REMOTE_USER=$1
|
|
|
|
<span class="kw1">DocumentRoot</span> /var/www/application
|
|
|
|
</<span class="kw3">VirtualHost</span>></pre>
|
|
<div class="notetip">Parfois, des applications PHP examinent également les variables d'environnement PHP_AUTH_USER et PHP_AUHT_PW. On peut les renseigner par la même voie :
|
|
<pre class="code file apache"><span class="kw1">SetEnvIfNoCase</span> Auth-<span class="kw1">User</span> <span class="st0">"(.*)"</span> PHP_AUTH_USER=$1
|
|
<span class="kw1">SetEnvIfNoCase</span> Auth-Password <span class="st0">"(.*)"</span> PHP_AUTH_PW=$1</pre>
|
|
|
|
<p>
|
|
Bien sûr, il faut <a href="passwordstore.html" class="wikilink1" title="documentation:2.0:passwordstore">stocker le mot-de-passe dans la session</a> pour renseigner PHP_AUTH_PW.
