Postfix, dovecot et LDAP

Bonjour tout le monde :)

J'essaie actuellement de mettre en place un serveur mail avec postfix et dovecot, le tout en utilisant une authentification LDAP.

Cependant, je rencontre quelques problemes :

L'authentification sur le serveur IMAP et STMP fonctionne très bien (testée avec thunderbird 3 et en telnet).

Auriez vous une idée de la cause du probleme ?
