Hello, Is putting "objectClass: top" is mandatory on every entry of ldif? I see sample from 2.1 admin guide did not include "top" # Barbara's Entry dn: cn=Barbara J Jensen,dc=example,dc=com cn: Barbara J Jensen cn: Babs Jensen objectClass: person sn: Jensen Some sample on the net always define "objectClass: top", which is "better"? Without define "objectClass: top" as in Admin guide, will it run on other Ldap server? TIA.
