Hi Corinna, sounds good. I'll give this a go, all being well, tomorrow. In other news it appears that the ADInsightDll uses some shared data to communicate, so in order to get ADInsight to work with injection one has to ensure that the DLL injected is the same actual *file* as the one loaded by the ADInsight program (in the (windows) %TEMP% directory) - a copy of the DLL doesn't seem to be effective.

As I just wrote in my mail to Dennis Hagarty, the performance improvement should be noticable, even with /etc/nsswitch.conf only using the "db" setting for groups. The group info for a user token with 150 groups was fetched in ~50 ms rather than the ~300ms of the former code. Can you test this again with the Cygwin DLL from the latest developer snaphshot at https://cygwin.com/snapshots/ please?
