Not that I can see, it simply seems to call stat64, which it did before. I don't think it drops any groups, either. And again, just mounting cygdrive with "noacl" gets rid of the problem entirely. > You're still using a group file?

I've just updated to the latest snapshot w/o AD integration for testing, will revert to the other one for more testing. Not sure if I can fit that in today, will send the links via PM when I have the traces uploaded.
