  Uh... upgrade.  1.1.2 is *very* old.  It's very likely that it won't
work with recent versions of Windows.  Fixes to work around Windows
"issues" went into later versions of the server, and aren't in 1.1.2.

Both certificates CA certificate, and server certificate was transferred to freeradius server and configured in eap.conf file in tls section. I made also other configurations to use peap protocol and mschapv2.

I checked all required options in connection properities like (use WPA2 with AES, PEAP, verify server certificate also with root CA certificate which was imported before). When I tried to connect from XP client everything is fine, client is authorized and connection works without problem. But from Windows 7 client its not. Same configuration, same settings, and I get error in radius.log:

  <shrug>  Those error messages are pretty definitive.

  In any case, I wouldn't bother trying to track down the problem.
Install 2.1.10, and then follow the EAP / Windows instructions on my web
site: http://deployingradius.com
