I have configured my WLC 4402 for Radius authentication using Cisco ACS server version 4.2 Patch 4.
When using Local Database of ACS my Wireless Users are able to authenticate but users are not able to authenticate from External Database of Windows AD 2008 R1.
In ACS logs I am getting the this error-
Authentication session timed out. Challenge not provided by client.
Thanks in advance,
Can you raise the service control to full and try again? You will need login into the machine (I am assuming acs for windows) and then analyze the auth.log and the rds.log and see if you are having any windows related errors in the auth.logs and see what the issue is in the RDS logs.
Which authentication protocol are you using? Leap, eap-tls. PEAP?
I am using PEAP authentication.
My Windows AD server is 2008 Standard SP2 and ACS Server is Win 2008 Standard Sp2.
Can you raise the service control to full and try again? The machine that ACS is installed on is that a member server or is it a domain controller?
