correct.

You should "glue" the databases together; in your case, the common root 
would be "".  See slapo-glue(5) if you're using OpenLDAP 2.3 or 
"subordinate" in slapd.conf(5) if you're using OpenLDAP 2.2.  I'm not 
100% sure gluing can occur with the empty DN, though.  If it's not 
possible, you may use back-meta (slapd-meta(5)) with empty "" at the end 
of your slapd.conf and as many targets as your databases are.
