<p>
There is 3 types of SQL configuration backends for LemonLDAP::NG :

<li class="level1"><div class="li"> <strong>RDBI</strong> : stockage en triplets</div>

<div class="level3">
<p>
Il faut autoriser l'accès en lecture et écriture pour le manager. Les autres composants n'ont besoin que d'un accès en lecture. On peut également utiliser le même compte pour tous.

<div class="notetip">Plusieurs chaînes dbiUser sont utilisables :<ul>
<li class="level1"><div class="li"> une avec des droits en lecture/écriture pour les serveurs hébergeant le manager</div>
</li>
<li class="level1"><div class="li"> une avec seulement des droits en lecture pour les autres serveurs</div>
