We really differ in opinion here.

Sorry, but I would not consider tconX to be a rare case.
I've got a trace of a busy IIS connected to Samba trying
tconX at a furious rate. Looking at the data model Jelmer
has chosen for reg_backend_ldb you need a onelevel search to
get all the values. I like this model because this way you
can live with large attribute values like security
descriptors, even if there are many of them.
