openldap/servers/slapd/back-ldbm/referral.c
Kurt Zeilenga 82fad7d0c8 First stable an implementing latest namedref specification.
Includes rewriting of URLs where the DN of the referral object
and the DN of the ref attribute attribute are not the same.
Also, always returns explicit DN and scope.
Currently, back-ldbm only.  Needs to be ported to back-bdb.
