This is not exactly what you are looking for, but I have put together screen shots of configuring Microsoft Network Policy Server RADIUS for use by administration. It may at least help you with the connectivity part.
first I would like to thank you for your support, actually the authentication works correctly with windows Radius server.
but,what I'm facing now that I have an ACS server from Cisco,and I tried to work with same manner as windows radius server,, but unfortunately the authentication does not work (authentication failed)...any ideas or suggestions ?!
