Description Sense Hofstede 2010-01-18 04:54:28 UTC

When mounting an NTFS (All FUSE devices affected?) device with DeviceKit it is mounted with the 'default_permissions' option. This limits access to the mounting user (and root) and breaks Samba sharing, because the client doesn't have the permissions to read the files in the directory.

This option is set when using 'devkit-disks --mount' and when using DeviceKit-disks from Nautilus.

Attached is the '/etc/mtab' file of the original reporter. The last entry was the device mounted by DeviceKit-disks, the entries above this last entry were mounted with the 'mount' command to illustrate the difference -- those two devices can be properly shared with Samba.

This bug was originally reported by JeongHo Park on Launchpad in Ubuntu at <https://launchpad.net/bugs/482641>.

udisks is not setting the default_permissions option. I think this is a problem with ntfs-3g or whatever ntfs filesystem driver you are using.
