Documentation for LDAP Mail Server

[David Snyder]

I want to setup a mail server on my FreeBSD box that runs Postfix and 
Cyrus that authenticates through OpenLDAP and have encryption (ssl?).  
Also, I'd like everything to be database backed... DB3 or DB4?  I can't 
seem to find anything on the internet that will show me how.

Does anyone have know where I can find such a tutorial or howto on the 
net or even a book that I could buy at a bookstore?

Thanks,
Dave
