[Exim] Exim authentication over ldap

    I'm trying to configure Exim in order to authenticate sender by querying a
ldap server. But I didn't find information on how to configure it. The
matter is that I wanted to configurate it to check the user and to allow the
delivery of the mail.

    I'm trying both exim 3.34 and exim 4.02, over Openldap2. But I don't manage
to relay even when I give a valid user and passwd. I have tried different
configuration (MD5, LOGIN, plaintext) but I wasn't able to make it work. Can
someone help me.

    Thanks.
