No, I didn’t. Thanks for the heads up.

However, I’m not sure I follow. If I’m not wrong, SSH agent forwarding is for logging into remote server B from remote server A without A having the credentials itself. How could that apply to sudo? Do you mean using a pam module like pam_ssh_agent_auth to authenticate the sudo user passwordlessly? I’m not familiar with this approach, but it seems to rely on ssh-agent running locally and reading a local authorized_keys file. I’m not sure if forwarding is relevant here?

I guess I probably have misunderstood. Could you share some tips on how that could be done?

Regards,
Glen
