That attribute is a 2008+ schema attribute, as far as I was aware when you provision with Samba your DC functionality is at 2008 R2 but forest/domain is at 2003 and can be raised to 2008 R2 try samba-tool domain level raise --domain 2008_R2 --forest 2008_R2 maybe that will add the attribute to the schema.
