bdb indexing limits

[Gaël Roualland <gael.roualland@oleane.net>]

Hello,

Looking through bdb code in OpenLDAP 2.3.x, it looks like for a specific 
index key, no more than 65536 entries are indexed, over which only the 
first and last potential matching entries are kept.

This is fine for most usages, but I have two questions :
- Is it reasonnably possible to augment this, should this create issues ?
- I noticed this limitation is also enforced on the entry children 
indexing, which means one you created more than 65536 children for an 
entry, you can no longer remove it ("non leaf" is returned), even after 
deleting all of its children first. This seems a bit annoying...
Would it be possible not to enforce it in that case ?

Thanks,

Gaël.
