That would be nice. I can explain and get rid of this "permission denied" message on Samba. What happens is that files are created under the uid of the Unix user you're authenticated as, not the uid/SID of your Windows user. `mv -f' calls chown to set the owner to your Cygwin uid which in turn tries to set the file's SID to your Windows user SID. That can't work, unless you have a uid<->SID mapping in your domain using winbind. As a result, the NT call trying to set the file owner returns with STATUS_INVALID_OWNER. I can catch this case for Samba explicitely. However, I can't do anything against a real ACCESS_DENIED sort of error as it is returned by your DFS. I see that it occurs at the same place where the Samba problame occurs, but that's it. I have no experience with DFS at all, and this would require to debug what happens in your environment. If you're willing to test, I would give you a special handcrafted Cygwin DLL which prints more detailed strace output to analyze what happens. I can't promise that this is a fixable situation, of course. Btw., can you run /usr/lib/csih/getVolInfo.exe from the csih package on your DFS drives (/ecn/groups and one of the others) and send the output to this list?
