The NX remote desktop software needs password-based authentication enabled.
This functionality will now be activated.  While you can still log in using your private
key file, please note that password authentication will now be possible both via NX and 
regular ssh for any user account which has a password set.

You can choose to set a password for $CURRENTUSER or give a new user name to create a
new non-privileged account.
