So what we need is a possibly hackish way to make this work
*now* with all the modules work on top off a slapd. If the
transactions are a concern, hack them into an extended
operation. Even if they stall all of the rest of OpenLDAP,
it won't be worse than what we have now. Then go and migrate
modules step by step. At some point in the future we then
might be able to make slapd listen itself on 389, but on the
way there we will benefit from OpenLDAP's better database
performance. If we have to solve module dependencies on
their way, that's going to be good for the code.
