Unfortunately that is a really ugly can of worms that you aren't likely to find a ready-made solution for in any language. The only option that really works is to use the Windows NT 3.5 security APIs in C, but those require you to manually marshal/unmarshal the data structures to/from flat buffers yourself. Windows NT 4 introduced some additional API functions that would have been easier to use, but they were never implemented correctly, at least up through and including Windows 2000. I can only assume that Microsoft stuck with the NT 3.5 security APIs for use in their own software. -mental
