As I noted above, the backend search won't be able to locate
an entry at the root as there is no entry at the root. Basically,
the special case needs to be added to handle e == NULL and
nbase == "".
There are two ways to handle the special case.
a) set e to a virtual root Entry
b) leave e == NULL and special case codes
to treat e == NULL as a search upon "".
I suggest a). Basically, inside of e == NULL conditional I would
add if( nbase is empty ) condition which would:
0) verify scope is not base
1) handcraft e as needed by search_candidates
2) call search_canditates
3) set realbase
5) jump to below cache_return_entry
The slimit/tlimit code would have to be relocated so as not
be jumped over.
Then it's a matter of ensuring the appropriate DN indices
have been generated and that the candidate code is correctly

I made changes so that one could add/delete top-level entries.
These changes are in HEAD and, IIRC, 2.0.6.
