ssh public key authentication

[Luca Ferrari]

Thanks all,
I've double checked my configuration, and the server was accepting rsa 
authentication, the key was right (I checked it with another user and it 
worked) and the permissions of the .ssh directory were right (0600). Then I 
had a look at the home directory of the user and I found that the group was 
not right, so I changed and the ssh login worked. So it is important not only 
the ownership and permissions of the .ssh directory, but of the whole home 
directory.

Thanks,
Luca
