Thanks for the reply Sam, I appreciate it.

Correct me if I am wrong, but if I get maildrop functioning, I do not even need 
to use Postfix (unless of course I want to)?

Correct.  You should be able to get some useful help on the Postfix list, 
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 
Courier-IMAP working correctly with OpenLDAP, via courier-authlib, then you 
could build maildrop, and end up using the same LDAP configuration 
automatically.  However you'll still need to address Postfix's configuration in 
some way.  Postfix will still need to use LDAP to at least check if the 
recipient address is valid, before accepting mail, rather than accepting 
everything, and get maildrop to bounce undeliverable addresses, which has 
certain security implications you'll want to avoid.

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