[winswitch] Unable to setup xpra proxy with authenticated xpra server

[Eric Grammatico]

Hello there !

I am going further in experiencing xpra proxy. I had successfully setup xpra proxy with opened xpra server. It works like a sharm. But once I tried to setup an xpra server authentication, it's like the proxy is passing a wrong user/password:

Command line from the proxy with logs:
$> xpra proxy :100 --daemon=no --bind-tcp=${HOSTNAME}:10000 --tcp-auth=multifile:filename=/home/proxy/.xpra/proxy_auth
