s4:kdc: Add asserted identity SID to identify whether S4U2Self has occurred
Because the KDC does not limit protocol transition (S4U2Self), two new
well-known SIDs are available to give this control to the resource
administrator. These SIDs identify whether protocol transition (S4U2Self) has
occurred, and can be used with standard access control lists to grant or limit
access as needed.
