Permission denied on SSHFS automount

Is your user a member of group fuse?

If not, please do:

~$ sudo adduser $USER fuse

Try to take a look at the permissions of the file:

~$ ls -l /etc/fuse.conf

It should be like this:

~$ -rw-r----- 1 root fuse 216 2011-05-18 07:12 /etc/fuse.conf

If not, please, correct it.

~$ sudo chmod 640 /etc/fuse.conf

Don't forget to logout and login again after adding your user to the group fuse.

Let me know if it solved your problem.

Regards.
