// The filter/augmentor routines use the following bits in a mask
// to track properties of IDs during logon. These bits have the following
// meaning:
//
// LSAP_AU_SID_PROP_ALLOCATED - Indicates the SID was allocated within
// the filter routine. If an error occurs, this allows allocated
// IDs to be deallocated. Otherwise, the caller must deallocate
// them.
//
// LSAP_AU_SID_COPY - Indicates the SID must be copied before returning.
// This typically indicates that the pointed-to SID is a global
// variable for use throughout LSA or that the SID is being referenced
// from another structure (such as an existing TokenInformation structure).
//
// LSAP_AU_SID_PROP_HIGH_RATE - Indicates it is expected that the SID
// will typically be used in ACLs to grant access. This is useful
// to know when arranging SIDs. Placing the IDs that will have a
// high chance of granting access at the front of the list of SIDs
// will reduce the amount of time spent in access validation routines
// after logon.
