It's great to see this feature getting implemented. One thing I was 
missing during a quick test is the "index" directive for back-bdb. But 
maybe that just not implemented right now. 

One thing I currently don't quite understand in the purpose of the 
olcIncludeFiles Objects. Is it planned to have the contents of include 
file available in the future as well? Or is it just to have the 
possibility to add/delete the includes? As long as one has only schema 
definitions in includes files this might be enough, but some people 
like to have other stuff there (e.g. to have the access rules in a 
separate file).

Yes, and IMO the same applies for the access control directives. I think 
that would make it more clearly laid out.
E.g. having "cn=access,olcDatabase={1}bdb,cn=config" for database 
specific ACLs and either "cn=access,olcDatabase={0}frontend,cn=config"
or "cn=access,cn=config" for global ACLs.

Hmm, I just recognized that at the moment global ACLs show up in both 
Objects (cn=config, and olcDatabase={0}frontend,cn=config). I guess 
this isn't wanted?
