If a client requests DELETE access and DELETE_ON_CLOSE in the create options and OPEN_IF or OVERWRITE_IF and the file does not exist (ie, it is to be created) and the parent directory where the creation is to occur does not give the requestor DELETE_CHILD, W2K08R2 still allows the open. Samba responds with ACCESS_DENIED. The new smb2.delete_on_close tests the relevant cases.
