I was pretty darn sure, IDM 3.6 engine ir2a, on SLES 10 that a query for
objectClass=posixGroup (by definition, always an aux class) should work.

But I am getting empty results back.

Query exactly the same for object Class of Group and it works.

I am really darn sure this ought to work, so am I going bonkers, or is
my memory flawed?
