RFC 2251 details the syntax and semantics of a referral result
and a search reference.  It, however, does not detail how subordinate
and other knowledge is actually held in the directory.  This was
left to future specifications.

OpenLDAP 2.0 implements an earlier version of the named ref I-D,
a work in progress:
        Named Subordinate References in LDAP Directories
        <draft-zeilenga-ldap-namedref-xx.txt>
2.0 code needs to be updated here and there based upon latest
revisions.

IIRC, most namedref revisions requires the server to rewrite
the DN as clearly the client should not.

Of course, if you are actually using LDAPv2++ referrals, things
gets quite messy.  Your mileage may vary here.
