I probably don't understand the nuances of ssh with sftp subsystem vs the sftp command but it seems to me that the sftp command somehow knows what needs to happen irrespective of us passing the password automatically or not. It knows when Authentication is complete and when it isn't since it knows when to wait and when to provide a working prompt to the user.

I can't hardcode the PreferredAuthentication since it is host specific and we do have a properly configured .ssh/config file with the appropriate Host specific overrides. It seems to me to get my setup working I will have to read the config file and figure out what the PreferredAuthentication is supposed to be for each Host which somehow feels like a wrong thing to do.

At this point I have no intention of using the password option since keyboard-interactive + publickey seems to cover every scenario that I am encountering - I will see how it goes by using a Unix.pm without the PreferredAuthentication override.
