The manual page of Xephyr says "The server accepts all the standard options of 
Xserver(1) and the following additional options". And manual page of Xserver 
has the "-auth" option.

Also Xephyr -help shows the -auth option.

If the -aith is not set, it won't use any auth file and let any client in.
