[Dovecot] dict ldap

Hello everybody,

Dovecot 2.2.6 with LDAP auth against AD (Samba4).

I would like to know if it's possible to specify an LDAP transport for dict (something like dovecot-dict-ldap.conf.ext). I'm in need to setup shared mailboxes and if I could query LDAP, that would help a lot. IE : user1 user2 user3 are in OU=group1, so group1 (setup as user in AD) would share its mailbox with user1 user2 and user3.

Thanks in advance for your time. Nicolas
