Comment 9 for bug 1574934

Hi all. I had the same issue with permissions and Transmission (Debian 9). Automounted cifs share in Gnome Nautilus works perfectly everywhere except Transmission.

Solved this issue by manually mounting with options:

sudo mount -t cifs //server/share /mountpath -o user=cifs_user,password=cifs_pw,uid=1000,gid=1000,iocharset=utf8

uid and gid belongs to desktop user you logging in and can be obtained by command:

id

or

cat /etc/passwd
