Because of the known problem with the OpenSSH on sp4, I've installed sp5 and
have the same problem in reading the remote file system. That's the reason
I've tried to move the user's home directories off the server to another
server in the tree (leaving the same file structure as on the origin server)
and to make the SSH connection (according to TID 10098889).

Finally, I've managed to reach my files showing they are on the second
server but it's NOT true because it shows the files on the origin server in
fact (I've checked that twice because the content of those folders aren't
the same in order to be able to see the difference).

So, I will very appreciate it if someone can explain this behavior of the
OpenSSH product.
