Henry, FYI, about the LoA in the Microsoft PAC part...NASA did make that request about 2 years ago. We had some follow-up and we asked for the capability to map a certificate issuance OID to a security group dynamically. Windows 2008 R2 does now have this capability. Some information about this is described here: http://technet.microsoft.com/en-us/library/dd378897.aspx I briefly piloted a demo in May with one of the prerelease builds. I was able to map id-fpki-common-authentication (from the PIV Auth certificate) to security group "PIV Authentication LOA 4", a security group of my choosing. I was then able to create standard Windows ACLs to restrict access to only users that authenticated with the PIV smartcard. There are some limitations. Microsoft does not yet have the capability to create ACL logical expressions, e.g. "Launch Control Team" and "PIV Authentication LOA 4". There are some work-arounds though.
