I am also looking at revising the handling of SACL information:

1) If the SACL is not going to be modified, the code should just leave 
it alone (do not specify SACL_SECURITY_INFORMATION)

2) If the SACL information IS going to modified / read, the code needs 
to acquire the SE_SECURITY_NAME privilege (and release it again ASAP)

Note that failure to do one or both of these things will result in an 
error if SACL_SECURITY_INFORMATION is specified to 
Get/SetNamedSecurityInfo when a SACL is present.  Files and folders 
report the error regarding necessary privileges, services report access 
denied, and I did not yet test registry keys.  The scheduled information 
will also need to contain the fact that we are not interested in the SACL.

Thanks,
