As I noted in another reply ealier this weekend, many times people,
including myself, set up the updatedn on a replica to be the same
as the rootdn.  If you do this, and test updates using the updatedn
(which equals rootdn) you won't get a referral.  Perhaps this is
why.

You can't do that.  Slapd is not designed to share the underlying database
with another slapd (except perhaps with back-sql as noted below, but even
then you would have caching/synchronization problems, since slapd is
expecting it to be sole modifyer of the underlying database).
