Out of curiosity, in your case, is the attribute you're indexing one that
would use caseIgnoreMatch?

Since I'm indexing a distinguishedName attribute, slapd appears to be using
caseIgnoreIndexer and caseIgnoreFilter to generate the keys to store/retrieve
by.

Unfortunately, at least with caseIgnoreFilter, it seems to be generating a
different key each time it is called with the same value.

I tossed the following into server/slapd/back-ldbm/filterindex.c in
equality_candidates():

        if (strcmp (dbname, "dalMailAliasOwner") == 0) {
           Debug( LDAP_DEBUG_TRACE,
                "   equality_candidates: key[0] = 0x%x\n", keys[0]->bv_val, 0, 0);
           Debug( LDAP_DEBUG_TRACE,
                "   equality_candidates: val[0] = %s\n", ava->aa_value->bv_val, 0, 0);
        }

And what I get is:

Am I looking at this the wrong way?
