<p>
<abbr title="LemonLDAP::NG">LL::NG</abbr> Slave backend relies on HTTP headers to retrieve user login and/or attributes.
</p>
<ul>
<li class="level1"><div class="li"> Authentication: will check user login in a header and create session without prompting any credentials (but will register client <abbr title="Internet Protocol">IP</abbr> and creation date)</div>
</li>
<li class="level1"><div class="li"> Users: collect data transferred in HTTP headers by the &quot;master&quot;.</div>
</li>
</ul>
<p>
It allows one to put <abbr title="LemonLDAP::NG">LL::NG</abbr>::portal behind another web <abbr title="Single Sign On">SSO</abbr>, or behind a SSL hardware to delegate SSL authentication to that hardware.
</p>
</div>

<div class="level2">
<p>
In Manager, go in <code>General Parameters</code> &gt; <code>Authentication modules</code> and choose Slave for authentication or users module.
</p>
<p>
Then, go in <code>Slave 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>Header for user login</strong>: header that contains the user main login</div>
</li>
<li class="level1"><div class="li"> <strong>Master&#039;s <abbr title="Internet Protocol">IP</abbr> address</strong>: the <abbr title="Internet Protocol">IP</abbr> addresses of servers which are accredited to authenticate user. This is a security point, to prevent someone to create a session by sending custom headers. You can set one or several <abbr title="Internet Protocol">IP</abbr> addresses, separated by spaces, or let this parameter empty to disable the checking.</div>
</li>
<li class="level1"><div class="li"> <strong>Control header name</strong>: header that contains a value to control. Let this parameter empty to disable the checking.</div>
</li>
<li class="level1"><div class="li"> <strong>Control header content</strong>: value to control. Let this parameter empty to disable the checking.</div>
</li>
<li class="level1"><div class="li"> <strong>Display authentication logo</strong>: display Slave logo.</div>
</li>
</ul>
<p>
You have then to declare HTTP headers exported by the main <abbr title="Single Sign On">SSO</abbr> (in <strong>Exported Variables</strong>). Example :
</p>
<div class="table sectionedit5"><table class="inline table table-bordered table-striped">
<thead>
<tr class="row0 roweven">
<th class="col0 centeralign"> Key (<abbr title="LemonLDAP::NG">LL::NG</abbr> name) </th><th class="col1 centeralign"> Value (HTTP header name) </th>
</tr>
</thead>
<tr class="row1 rowodd">
<td class="col0 centeralign"> uid </td><td class="col1 centeralign"> Auth-User </td>
</tr>
<tr class="row2 roweven">
<td class="col0 centeralign"> mail </td><td class="col1 centeralign"> User-Email </td>
