Dbmail-2 as of 2.1.0 supports ldap for authentication and delivery information.


NOTICE:

If you have an existing userbase in sql that you which to migrate to ldap-auth, you 
must make sure that the uidNumber in ldap is the same as the dbmail_users.user_idnr 
in sql. If your tables are in MySQL/innoDB or PostgreSQL, and you have a proper cascade 
setup for the foreign key in dbmail_mailboxes like:

 CONSTRAINT dbmail_mailboxes_ibfk_1 FOREIGN KEY (owner_idnr) 
  REFERENCES dbmail_users (user_idnr) 
  ON DELETE CASCADE ON UPDATE CASCADE

you should be able to issue simple UPDATE statements to reset the user_idnr values in sql.
