I just moved from a windows 2003 IAS server over to window 2008 NPS and I am getting this message on the WLC. AAA Authentication Failure for UserName:VESLABCT10_15DO\Administrator User Type: WLAN USER. this is a test user. I double checked the password both for NPS and WLC. It worked great under windows 2003 IAS. I installed certifcates services on the windows 2008 and exported the certificate and install the certificate on the client. Any suggestions
