Ok, I see.

We have on our roadmap (after 1.0) the straight forward optimization only to 
rewrite those files which really need changes whenever something changes in 
LDAP.

I was especially thinking about very large installations and I am wondering if 
a local db based on a file is not much faster than LDAP queries for postfix.

This is the reason why I think that it is possible that introducing direct 
LDAP support for postfix is maybe the wrong solution for the potential 
scalability problem.
