ssh -A, which allows me to use my local ssh key when establishing a connection from a remote server. For example, I
ssh -A host1.example.com and then from there I can
ssh host2.example.com (or use git) and it uses my ssh key from the original machine, which in this case should be my mac. Although this has always worked for me on Debian/Ubuntu, it doesn't work on my new mac (Lion).
What am I missing here? How do I configure ssh to work correctly with -A? Do I need an ssh that is not the standard MacOS one?
