I want to have an SSID that does RADIUS authentication against a Server 2012 R2 RADIUS server.
This currently works with my Procurve setup, but I'm having issues making it work with the Aruba AP.
I've been following this guide, but so far, no luck. http://www.arubanetworks.com/techdocs/InstantMobile/Advanced/Content/External%20RADIUS%20Server.htm
The error on the server 2012 side is
Reason Code: 16
Reason: Authentication failed due to a user credentials mismatch. Either the user name provided does not map to an existing user account or the password was incorrect.
But, the credentials are being pulled from the Windows session, so they're correct.
