I have a number of users of a desktop machine, who each have a folder on a remote samba server. I am trying to set up per-user mounting of these network folders following the instructions here:
That article recommends adding the following line to sudoers:
user ALL= NOPASSWD: /bin/mount -t cifs -o cred=/home/user/.Music.cred //server/music /home/user/MyMusicFolder
That command works fine, but I need to mount the shares so that they are owned by a specific group. I have tried changing the line to read like this:
user ALL= NOPASSWD: /bin/mount -t cifs -o cred=/home/user/.Music.cred,gid=xxx //server/music /home/user/MyMusicFolder
But with the addition of the ,gid=xxx the sudoers file no longer parses correctly. I assume this is because the NOPASSWD command actually takes a comma separated list of arguments so I need to escape the comma in the command. I can do this using a backslash, like so:
user ALL= NOPASSWD: /bin/mount -t cifs -o cred=/home/user/.Music.cred\,gid=xxx //server/music /home/user/MyMusicFolder
Now the sudoers file will parse, and I can run the mount command with sudo without being asked for a password. Unfortunately I now get this error:
Sorry, user is not allowed to execute '/bin/ls /home/' as root on ubuntu.
when I try to run any other command. I don't get this error if I remove the
\,gid=xxx from the line. So what is the right way to escape commas in the sudoers file?
