 H1: Backends
 
+Backends do the actual work of storing or retrieving data in response
+to LDAP requests. Backends may be compiled statically into {{slapd}},
+or when module support is enabled, they may be dynamically loaded.
+
+If your installation uses dynamic modules, you may need to add the
+relevant {{moduleload}} directives to the examples that follow. The
+name of the module for a backend is usually of the form:
+
+>	back_<backend name>.la
+
+So for example, if you need to load the {{hdb}} backend, you would configure
+
+>	moduleload back_hdb.la
