Correct. You should be able to get some useful help on the Postfix list,=20
that's the best place to get help on configuring Postfix to use LDAP.

Now, since you indicate that you already have the current version of=20
Courier-IMAP working correctly with OpenLDAP, via courier-authlib, then=20
you could build maildrop, and end up using the same LDAP configuration=20
automatically. However you'll still need to address Postfix's configurat=
ion=20
in some way. Postfix will still need to use LDAP to at least check if th=
e=20
recipient address is valid, before accepting mail, rather than accepting=20
everything, and get maildrop to bounce undeliverable addresses, which has=20
certain security implications you'll want to avoid.

Generally, LDAP is a pain even for people who've been around the block mo=
re=20
than once. Generally, you do not want to learn two things at once, when =
one=20
of the is LDAP. You'll want to learn how to use and set up Courier and=20
Postfix first, with LDAP completely out of the picture. Then, when you k=
now=20
what you're doing, you can start fighting with LDAP. But doing both at o=
nce=20
is going to be a tough road to haul.
