<p>
We will explain how to use <a href="http://www.mediawiki.org/wiki/Extension:AutomaticREMOTE_USER" class="urlextern" title="http://www.mediawiki.org/wiki/Extension:AutomaticREMOTE_USER" rel="nofollow">Automatic REMOTE_USER</a> extension.

The extension is presented here: <a href="http://www.mediawiki.org/wiki/Extension:AutomaticREMOTE_USER" class="urlextern" title="http://www.mediawiki.org/wiki/Extension:AutomaticREMOTE_USER" rel="nofollow">http://www.mediawiki.org/wiki/Extension:AutomaticREMOTE_USER</a>

<p>
You can download the code here: <a href="https://www.mediawiki.org/wiki/Special:ExtensionDistributor/Auth_remoteuser" class="urlextern" title="https://www.mediawiki.org/wiki/Special:ExtensionDistributor/Auth_remoteuser" rel="nofollow">https://www.mediawiki.org/wiki/Special:ExtensionDistributor/Auth_remoteuser</a>
</p>
<p>
You have to install <code> Auth_remoteuser</code> in the <code>extensions/</code> directory of your MediaWiki installation:
</p>
<pre class="code">cp -a Auth_remoteuser/ extensions/</pre>

<!-- EDIT4 SECTION "Configuration" [986-1012] -->
<h3 class="sectionedit5" id="mediwiki_local_configuration">MediWiki local configuration</h3>
<div class="level3">
<p>
Then edit MediaWiki local settings
</p>
<pre class="code">vi LocalSettings.php</pre>
<pre class="code file php"><span class="kw1">require_once</span> <span class="st0">&quot;<span class="es4">$IP</span>/extensions/Auth_remoteuser/Auth_remoteuser.php&quot;</span><span class="sy0">;</span>
