The steps you took show that you are NOT following the guide. Good luck. You clearly are *not* interested in solving the problem.
the guide in radiusd.conf says: #The server has proxying turned on by default. If your system is NOT # set up to proxy requests to another server, then you can turn proxying # off here. This will save a small amount of resources on the server. I tried to read carefully with undrestanding, I dont use proxy, my system not sending request to another server, so I turned it off.
You might not want to, but you *are* proxying your requests. You have created client certificate with predefined data in client.cnf - which is part of the proxy demonstration setup. So, leave proxy settings alone and concentrate on doing what you have been advised - changing data in client.cnf so created client certificate won't have @example.com as part of the username.
