Dear Mathieu, sorry for the late reply. > Are you able to reproduce this bug on latest buster (2:4.9.4+dfsg-2 or -3)? Yes, I still can reproduce it on latest buster with samba 2:4.9.5+dfsg-4 .
> If yes, can you provide your smb.conf? However, now the bug seems to only show up if I set path=/ (and then of course first navigate to the tmp directroy in windows explorer) instead of path=/tmp in the [share] section of the smb.conf provided in my initial post. Again setting wide links = Yes and allow insecure wide links = Yes functionally helps, although this should not be necessary as even /tmp is an ordinary subdirectory of / and no different/mounted file system. (To get 100% sure of the latter I also created another top level directory /mytopdir next to /tmp with the same results.) Thank you for your interest and help, Chris
