generationQualifier

Hi -

i recently upgraded to OpenLDAP 2.1.18 and when I try to import some 
data using ldapadd, it keeps balking on the generationQualifier 
attribute.  The following error comes up:

 ***** ERROR MESSAGE  *****
adding new entry "uid=mengelhart, ou=Administrator, ou=Sales, 
ou=People, o=somecompany.com"
ldapadd: update failed: uid=mengelhart, ou=Administrator, ou=Sales, 
ou=People, o=somecompany.com
ldap_add: Object class violation (65)
        additional info: attribute 'generationQualifier' not allowed

and relevant portion of slapd.conf

include         /usr/local/etc/openldap/schema/core.schema
include         /usr/local/etc/openldap/schema/cosine.schema
include         /usr/local/etc/openldap/schema/inetorgperson.schema
include         /usr/local/etc/openldap/schema/openldap.schema

Any help as to why I can't use an attribute type that's part of the 
core.schema, I'd greatly appreciate it.

Thanks

Michael
