LemonLDAP::NG is highly scalable, so easy to insert behind a load-balancer:
</p>
<ul>
<li class="level1"><div class="li"> Portal does not store any data outside the session database, so you can have many portal servers using the same HTTP host name</div>
</li>
<li class="level1"><div class="li"> All handlers download the whole configuration, so many servers can serve the same virtual hosts</div>
</li>
</ul>
<p>
You can for example set up a fail-over cluster with <a href="http://www.linux-ha.org/wiki/Heartbeat" class="urlextern" title="http://www.linux-ha.org/wiki/Heartbeat" rel="nofollow">Heartbeat</a> and <a href="http://haproxy.1wt.eu/" class="urlextern" title="http://haproxy.1wt.eu/" rel="nofollow">HAproxy</a>, like this:

</p>
<p>
You just have to share configuration and sessions databases between those servers:
