The slaves do not need to see the server (actually, they don't even
know they are slaves except for they refuse write operations unless
the writer has a special DN); in fact OpenLDAP tools use a "push"
replication scheme (as inherited from UMich's slapd), where the master
"pushes" changes to the slaves.

It looks like your clients are actually contacting the master
and totally ignore the slave.  IMHO, you should work on this.
