In any case, with currently released code there is no way to update the
consumer. One thing you can do is to add a global instance of
slapo-chain which redirects writes to the producer. To the client, it
will appear like updating the consumer (but updates will get to the
consumer later, possibly after the client got a successful response, so
immediate reads could not see the modifications in place yet).
Example configuration is produced by running test007 and test018 (look
at "overlay chain" in the consumer's slapd.conf).
OpenLDAP 2.4 will allow mirror mode setups which means that multiple
servers will simultaneously act as masters. But that's not released yet.
