Have you actually checked to see that the file test2 really > isn't group writeable? Maybe worth a quick test. I just tested it with another user and no, the file is really not group-writable. But I found another really mysterious behaviour... This time I’ve connected as user "steffi" who is in the "share" group as well: % sudo mount //avalon/share -t cifs -o user=steffi,gid=quintus /mnt I tried to create a file now as this user: ---------------------------------------------------- (1067) [9:28:47 quintus@hades] /mnt % ls -ahl total 4.0K drwxrws---+ 2 root quintus 0 Mar 28 09:28 . drwxr-xr-x 20 root root 4.0K Mar 19 17:32 .. -rw-rw----+ 1 quintus quintus 0 Mar 26 14:54 test -rw-r-----+ 1 quintus quintus 0 Mar 26 15:04 test2 (1068) [9:29:29 quintus@hades] /mnt % touch test3 touch: cannot touch ‘test3’: Permission denied (1069) [9:29:34 quintus@hades] /mnt % ls -ahl total 4.0K drwxrws---+ 2 root quintus 0 Mar 28 09:29 . drwxr-xr-x 20 root root 4.0K Mar 19 17:32 .. -rw-rw----+ 1 quintus quintus 0 Mar 26 14:54 test -rw-r-----+ 1 quintus quintus 0 Mar 26 15:04 test2 -rw-r-----+ 1 1002 quintus 0 Mar 28 09:29 test3 ---------------------------------------------------- That is, I get a "permission denied" on the "touch" command, but the file is there nevertheless...? How is this possible at all? Even worse, I cannot write to the file I just created: (1070) [9:29:35 quintus@hades] /mnt % echo foo > test3 zsh: permission denied: test3 And no, the file is really empty (I’ve chceked it on the server via SSH). Writing to the files owned by someone else, but still in the "share" group doesn’t work either: (1071) [9:31:19 quintus@hades] /mnt % echo foo > test2 zsh: permission denied: test2 And again, this file really is empty. On the server, the permissions are reported like this: ---------------------------------------------------- (433) [9:33:34 quintus@avalon] /srv/cifs/share % ls -ahl insgesamt 8,0K drwxrws---+ 2 root share 4,0K 28.
