Got this working.  I was already doing the above, but the account was
protected by a passphrase.  I since deleted the passphrase, and
everything works fine.  I am still a little worried about security,
since enyone who has access to
the identity.pub file can now log into the remove machine.  Embedding
passwords
in scripts, however, introduce their own sort of security holes.

Thanks,

Andrew
