<abbr title="LemonLDAP::NG">LL::NG</abbr> can delegate authentication to a <abbr title="Central Authentication Service">CAS</abbr> server. This requires <a href="http://sourcesup.cru.fr/projects/perlcas/" class="urlextern" title="http://sourcesup.cru.fr/projects/perlcas/" rel="nofollow">Perl CAS module</a>.
</p>
<div class="notetip"><abbr title="LemonLDAP::NG">LL::NG</abbr> can also act as <a href="idpcas.html" class="wikilink1" title="documentation:2.0:idpcas">CAS server</a>, that allows one to interconnect two <abbr title="LemonLDAP::NG">LL::NG</abbr> systems.
</div>
<p>
<abbr title="LemonLDAP::NG">LL::NG</abbr> can also request proxy tickets for its protected services. Proxy tickets will be collected at authentication phase and stored in user session under the form:
</p>
<p>
<code>_casPT</code><strong>serviceID</strong> = <strong>Proxy ticket value</strong>
</p>
<p>
They can then be forwarded to applications trough <a href="writingrulesand_headers.html#headers" class="wikilink1" title="documentation:2.0:writingrulesand_headers">HTTP headers</a>.
</p>
<div class="notetip"><abbr title="Central Authentication Service">CAS</abbr> authentication will automatically add a <a href="logoutforward.html" class="wikilink1" title="documentation:2.0:logoutforward">logout forward rule</a> on <abbr title="Central Authentication Service">CAS</abbr> server logout <abbr title="Uniform Resource Locator">URL</abbr> in order to close <abbr title="Central Authentication Service">CAS</abbr> session on <abbr title="LemonLDAP::NG">LL::NG</abbr> logout.
