[linux-cifs-client] mount.cifs permission denied problem

[Marco Stornelli]

With nounix option works but only if I mount with dir_mode=0777 and
file_mode=0777. However user1 can access to the folder2 of user2. It's
not very useful. If I mount with dir_mode=0755 and file_mode=0755, it
doen't work, I still have permission denied.
