[winswitch] Xpra proxy with --auth=allow does not work

[Mukul Agrawal]

I am running xpra server 0.15 that I got from the latest winswitch repo.
Started proxy like that shown in your basic usage example ProxyServer – Xpra

xpra proxy :13 --bind-tcp=0.0.0.0:10000 --auth=allow
started a xpra server instance on same machine/same account using several different formatsxpra start :11
xpra start :11 --bind-tcp=127.0.0.1:10001
xpra start :11 --auth=allow --bind-tcp=127.0.0.1:10001
When I try to attach to this instance from windows machine using
Xpra_cmd attach tcp/user at IP/10000/11  

I get authentication error :- " authentication failed: this server requires authentication, please provide a password."

Another problem
xpra stop :13 will not stop the proxy.I again get a message asking for a password.
