What do you see in the logs on the server, from sshd? Does it report anything when an authentication fails?

I isolated Capistrano from the environment by creating a simple
Net::SSH script that makes one call via ssh:

#! /usr/local/bin/ruby

require 'rubygems'
require 'net/ssh'

 output = ssh.exec!("hostname")
 puts output
end

This is where all the issues lie, as I get exactly the same error.

executed by some account OTHER than "tools," following a standard
password prompt.
