objectclass not found inetorgperson?

I keep getting a ldap_add: Invalid syntax (21) additional info: objectclass: value #0 invalid per syntax

(ldif) dn: cn=Charlton Heston,ou=people,dc=afranius,dc=com cn: Charlton sn: Heston mail: heston@actor.com telephoneNumber:508-555-1212 objectclass: inetOrgPerson

slapd.conf's include /usr/local/etc/oplenldap/schema/core.schema include /usr/local/etc/oplenldap/schema/cosine.schema include /usr/local/etc/oplenldap/schema/inetorgperson.schema

it successfully added the two objects prior to this, do you guys have any ideas what might be going on?

Thanks! *Ray*
