Yip Ng updated DERBY-1686:
--------------------------

    Attachment: derby1686-trunk-stat06.txt
                derby1686-trunk-diff06.txt

Attaching derby1686-trunk-diff06.txt.  There was conflict with the latest code trunk's master file for grantRevokeDDL.sql, so resubmitting the patch.  It should apply cleanly.

> With authentication on, attempting to execute a GRANT privilege  to 'user3' on a VIEW created by the 'user2' - who has only SELECT privilege
> on the base table created by 'user1' does not fail. This results in 'user3' getting access to the table created by 'user1' through the view.
> I remember a discussion on the list to raise an error when an attempt is execute a GRANT on the view, until WITH GRANT option is implemented.
