SSH forwarding doesn't work

[RonenHoffer]

Using the -A option isn't forwarding the ssh agent.

Running with regular ssh command
Running presto-admin file run /path/to/file -A (the file has a env command)

ssh -A [e-mail] -C "env"

You can see that the SSH_AUTH_SOCK is missing

We use ~/.ssh/config to set ForwardAgent.
