I have a FreeNAS installation running under VirtualBox. When I try to mount one of my FreeNAS shares in Ubuntu 12.10, permissions on the share prevent me from entering the directory, listing or creating files.
My intention was to provide a share where the FreeNAS john account has full authority, and the barbara and mark accounts have read-only access. However the permissions of the mounted share pevent me from even listing the directory, let alone create or read any files there.
Am I doing something wrong when mounting the share?
I will try to provide more information below.
I set up my FreeNAS according to the instructions found here. The resulting storage has permisssions as shown here:
(I know I need to tweak the write-permissions for the group.)
Under Windows7, I have no problems mounting the share:

However, attempting to do the same under Ubuntu doesn't work as well:

Note the permissions & owner of /mnt/tunes above. It is about to change, though I don't know if that's expected/correct.

1001 is the uid for john on my FreeNAS, and 1003 is the gid for users there. john should have full access.

ls: cannot open directory /mnt/tunes: Permission denied

What am I doing wrong here?
Best Answer
write the mount (/etc/fstab in this case) with noperm parameter to instruct local client ignore permission checks. It look like this (works for me,o nce i had ignored local permission rights)
