You should not be using a release that old in production.

The HDB backend is deprecated and generally should be avoided for use.

You should also use a current release of OpenLDAP.

As for "olcBackend" that's a Debian oddity and should hopefully be removed 
some time in the future.

Generally, one:

a) olcModuleLoad's the overlay and/or backends needed
b) declares a database, i.e., olcDatabase ...
c) instantiates overlays on that database (olcOverlay=..,olcDatabase=... 
etc)
