ok, there has been some confusion between LsarLookupRIDs and
LsarLookupSIDs.  i will look at separating these two properly tomorrow,
and hopefully coax an LsarLookupRIDs call out of NT :-).

to get a LsarLookupSIDs call (and a core dump :-) you do File | Properties
| Security | Permissions and the dialog there initiates a lookup of the
SID to a name to display.
