Package: thunar Version: 1.6.3-2 Severity: normal Dear Maintainer,
I have some password protected shares in my /etc/fstab that are mounted by unprivileged users, e. g. > //192.168.1.2/Data /media/Data cifs > vers=3.0,users,username=user,noauto,file_mode=0640,dir_mode=0750 0 0 When mounting the share with the 'mount' command a password is prompted as intended. However, mounting the share with thunar fails: On the first access thunar tries to mount the share and a graphical password prompt *should* appear. Instead an error message is shown: > Failed to create password file: Permission denied After some investigation I found out that the ask-password functionality from systemd is used. Therefore a file has to be created in /run/systemd/ask-password and password agents watching the directory might prompt for the password. See [1] for reference. Creating the password file fails, as /run/systemd/ask-password is only writable by root. As this functionality is intended to be used for system-level passwords only, I guess it shouldn't be world writable. To mount the volume, thunar seems to rely on libglib2 (Thunar calls g_volume_mount). See [2], [3] for the source code. I don't really understand how that code works and why systemd ask-password is used - I didn't manage to find the corresponding code. Im not sure if this bug can be fixed in thunar or if either systemd or glib2 are to blame, but I hope you can help to track down the root cause. Probably systemd shouldn't be used at all for mounting shares in thunar. To reproduce this bug you don't need an actual share - you can add a fake entry to your fstab.
