Sorry about your frustration, we are just trying to narrow it down. It could be that something in artful's samba changed and that thunar needs to adapt, for example.
We need to determine why this test case that you mentioned when opening the bug doesn't work: """ 16.04 client mount.cifs to 17.10 server: access denied error """ This doesn't involve thunar and is bare bones cifs/samba. Please try the following on this 16.04 client. Adjust username if needed, and replace "<artful-server>" with your artful server's IP address: sudo mkdir -p /artful/{Home,Maps,Media} for d in Home Maps Media; do sudo mount //<artful-server>/$d /artful/$d -o username=patrick; done If they get mounted, check what you can do in each /artful/* directory in terms of read/write. If the above works, then I need to know the exact commands you tried for the above test case you tried and that failed. I suppose it's whatever you did to get to the mounted share you showed in comment #5, and then which read/write commands you tried and their outcome.
