Where should I specify the ordering rule for the uid attribute? The
core schema?
I believe I have this issue as well. Since upgrading to OL 2.4.20 our
OpenFire XMPP server has been logging an unending stream of -

No changes were made to the OpenFire configuration, so the issue must be
do to a change in OL schema.  Browsing our DSA's schema and cn and uid
have no ordering rule.

Setting the OpenFire server property "ldap.clientSideSorting" to "true"
seems to have cleared up this issue.  Without that property OpenFire was
requesting the control 1.2.840.113556.1.4.473 on the "uid" attribute.

Not sure what you're pointing out here. OpenLDAP doesn't advertise server-side sorting by default, you have to explicitly configure the overlay to get it. So there's no way that just upgrading to 2.4.20 would have suddenly caused this problem to start.
