indexes and bdb backend

[dju` <dju.ml@elegiac.net>]

Hi,

is it possible to use the index directive for a bdb backend? from what 
i've read from the openldap manual, i should do so, but i often see them 
used in bdb backends. i've tried to set some, but searches return no 
results with.

Thanks for help.
