HI!
Not sure whether this has discussed before.
I have to deal with a third-party application where single entries are read by sub-tree search with filter (entryDN=<DN>). That cannot be easily changed. The database is rather small (<10000 entries) so I simply tried to generate an equality index for entryDN which does not seem to be possible (slapd shows error message when reading config).
So I wonder whether this sort of filter is already optimized out with the dn2id.bdb index.
Ciao, Michael.
