Then next on my list is to add a local db search to translucent.c so you
can search for attributes not just on the remote db.
I think this was already discussed. I think a big issue about that is
that with complex filters (even with simple, if part of the values is
local and part remote) need local + remote data knowledge at candidate
selection. As a consequence, there's no (simple) way search candidates
can be selected if part of the filter relies on local data. I don't see
this an easy task from a theoretical point of view, not just in terms of
implementation. For example, this is basically what prevents back-meta
from building entries by joining partial entries residing on different
remote servers.
