I am setting up wireless with certificates but I am having an issue with the "Authentication Mode". If I choose "User re-authentication" under the security tab (second screenshot) it fails with the error "No credentials are available in the security package" but if I choose "Computer Authentication" it works fine.
I don't understand why I can't use "User re-authentication". Here's some screenshots to help show the configuration of NPS on Windows 2008 and the client is Windows 7 with group policy. The error at the end is from the Event Viewer.
