<a href="http://www.w3.org/wiki/WebID" class="urlextern" title="http://www.w3.org/wiki/WebID" rel="nofollow">WebID</a> is a way to uniquely identify a person, company, organisation, or other agent using a <abbr title="Uniform Resource Identifier">URI</abbr> and a certificate.
</p>
<p>
You need <a href="https://metacpan.org/release/Web-ID" class="urlextern" title="https://metacpan.org/release/Web-ID" rel="nofollow">Web::ID</a> package.

In Manager, go in <code>General Parameters</code> &gt; <code>Authentication modules</code> and choose WebID for authentication module. You can also use WebID as user database.
</p>
<p>
Then, go in <code>WebID parameters</code>:
</p>
<ul>
<li class="level1"><div class="li"> <strong>Authentication level</strong>: authentication level for this module.</div>
</li>
<li class="level1"><div class="li"> <strong>WebID whitelist</strong>: list of space separated hosts granted to host FOAF document. You can use &#039;*&#039; character. Example :<pre class="code">*.partner.com</pre>
</div>
</li>
</ul>
<p>
If you use WebID as user database, declare values in <strong>exported variables</strong> :
</p>
<ul>
<li class="level1"><div class="li"> use any key name you want. If you want to refuse access when a data is missing, just add a “!” before the key name</div>
</li>
<li class="level1"><div class="li"> in the value field, set the field name. Take a look at <a href="http://xmlns.com/foaf/spec/#sec-crossref" class="urlextern" title="http://xmlns.com/foaf/spec/#sec-crossref" rel="nofollow">http://xmlns.com/foaf/spec/#sec-crossref</a>. Example :<pre class="code">name =&gt; foaf:name</pre>

Portal host must be configured to use SSL and must ask for client certificate. It is recommended to use optional_no_ca since WebID doesn&#039;t use certificate authorities :
</p>
<pre class="code file apache">&lt;<span class="kw3">VirtualHost</span> _default_:<span class="nu0">443</span>&gt;
<span class="kw1">ServerName</span> auth.example.com

<span class="kw1">SSLCertificateFile</span> ...
