Arvados

We recently had a user attempt to follow these instructions:

https://doc.arvados.org/user/getting_started/ssh-access-windows.html

Running "plink -P 2222 turnout@switchyard.qr1hi.arvadosapi.com %host" as per the docs, results in an "Access granted" message, followed by "Access to host disallowed for user" after pressing return.
