This is strange.
My WLC 5508(runing on ver 6) works well with a WIN2003 Radius server for wireless users authentication. Recently, our IT team built another Radius server on WIN2008. They replicated all Radius settings, passwords. And the new WIN2008 Radius server works fine with my ASA Firewalls for VPN users authentication. But, the WLC5508 just doesn't work with the WIN2008 Radius server, it always gave me 'Authentication failed' message when we tested it. We tried many things, checked setting details many times to make sure they match, but jsut cannot make it working.
Can someone give me some advises, what I should do now? why the new WIN2008 Radius server can work with my ASA, but just not my WC5508?
Thanks a lot.
