I'm trying to use Net::OpenSSH with the ssh -oProxyJump=user@bastionhost option to jump the connection through an intermediate bastion host. However, I can't get the authentication to work. The built in authentication only does one password prompt. So I'm trying to use login_hander => custom_login_hander option, and a custom handler subroutine that recognizes the password prompt and gives the right password for that stage. It works for the first hop. However, Net::OpenSSH seems to only fire the custom handler once. It seems to never call it on the second password prompt. Can anyone suggest anything?

I've got a workaround of calling the ssh binary, with the flags I need, and Expect-ing my way through the prompts. But it seems overly complicated.
