Basically, you need to set up sshagent so that you don't get prompted for a password/passphrase. Here are two article explaining how:

http://mah.everybody.org/docs/ssh

and

I made a few mod's to your sshd_config your ssh_config should not matter. This is for the simplest type of trusted authentication. You should look at getting O'Reily's SSH book.

In the users .shost file add
hostname username
note: may need hostname(FQDN)

establish the key's both way
then do a ssh -v and watch the output for any errors
