We need to filter out the SEC_DESC_DACL_AUTO_INHERITED|SEC_DESC_DACL_AUTO_INHERIT_REQ bits. If both are set we store SEC_DESC_DACL_AUTO_INHERITED as this alters whether SEC_ACE_FLAG_INHERITED_ACE is set when an ACE is inherited. Otherwise we zero these bits out. See: http://social.msdn.microsoft.com/Forums/eu/os_fileservices/thread/11f77b68-731e-407d-b1b3-064750716531 for details.
