From the ssl man page
-l login_name: Specifies the user to log in as on the remote
machine. This also may be specified on a per-host basis in the
configuration file.
This is not a problem with the autotest user on your machine. What
probably happens is you do not have ssh key properly setup.

Host Installation Steps
Setup password-less ssh connection from the server to this host
On the server, create a DSA key in the following way:
ssh-keygen -t dsa
Then, still on the server, copy it to the host:
ssh-copy-id [email protected]
I'm rejecting this patch.
