I am looking for the latest version of the Windows header file <sddl.h> that contains cnstants related to Vista's Mandatory Access Control and to Process Isoation.
Does anyone have it or knows how to get it? Is such file available from Microsoft?

The speciifc definitions I am looking to get from this file are:
* String constants to construct SACL ACE for Mandatory Access Control
* Constants like SDDL_IL_LOW, SDDL_IL_MEDIUM, SDDL_IL_HIGH
* Any SDDL ACE declarations/definitions that might be related to the activation of running COM/DCOM servers from various Integrity Levels

I'd appreciate any help,
