[Dovecot] Informations in LDAP and Database

Hi everybody,

I'm installing an application using LDAP and I want dovecot to use LDAP too. The problem is that they don't use the same schema (especially because we want per-user quotas). I think the best solution is to have the authentication by LDAP and others datas (like quotas) in a database.

Is it possible with dovecot ? and How ?

Thanks Etienne
