[Dovecot] LDAP: bind to LDAP server instead of retreiving a password from it?

[Geert Hendrickx]

Hi, 

Dovecot currently treats an LDAP user/password database the same way as a text
or SQL based database: it just tries to retreive the (hashed) password for a
given username.  LDAP however has the capability to authenticate the user
itself: dovecot could try to bind to LDAP with the given username and password,
and if authentication succeeded, the LDAP server returns the other info (uid,
homedir, ...), but not the password. I know at least qmail's pop3 server uses
LDAP this way.  Could this authentication mechanism be implemented in Dovecot
as well?
