Not all of OpenLDAP's backends support all controls. Which backend are 
you using? It's probably easiest just to send your config file 
(slapd.conf, but remember to remove sensitive data like passwords!).

As a side note, 2.3.19 is now a very old version! You really should 
upgrade, at least to 2.3.43.
