I recommend against LDAP for users who don't already use LDAP for other
reasons. While LDAP reads may in some cases be faster, often they are not.
Lack of proper transactions in LDAP makes managing the data much harder
and this is more important IMHO. If you want a dedicated datastore for
Postfix built from scratch use PGSQL or MySQL. If you have a corporate
white pages based on LDAP, use that.
