From the phone, contacts could be found. But now not anymore, due to a bug in the system. I had to remove the Application IP-address and DNS-name from PBX\General. Otherwise, myApps wasn't functioning on from remote locations.

And the Reverse Lookup URL is configured:

ldaps://apps.weseedo.nl/dc=entries?givenname,sn,company?sub?(metaSearchNumber=+%n)?bindname=weseedo.nl\contacts
