Your question is not strictly related to OpenLDAP software, unless you
mean whether OpenLDAP's slapd requires an entry to have the objectClass
"top" or not.  All objectClasses inherit from "top"; recent versions of
OpenLDAP's slapd (2.2 for sure; I'm pretty confident 2.1 does as well)
honor objectClass inheritance, so all objectClasses defined in the schema
must directly or indirectly inherit from "top", so your entries will be
fine as soon as you provide exactly one structural objectClass in all of
your them, and you'll be able to search for "(objectClass=top)" or assert
"objectClass:top" in compares and so.
