Cisco ISE authentication failed because client reject certificate

Question

Hi Experts,
I am a newbie in ISE and having problem in my first step in authentication. Please help.
I am trying to deploy a standalone Cisco ISE 1.1.2 with WLC using 802.1x authentication. The user authentication configured to be checked to ISE's internal user database for early deployment. But when the user try to authenticate, they failed with error message in ISE :
Authentication failed : 12321 PEAP failed SSL/TLS handshake because the client rejected the ISE local-certificate
I've generate a certificate for ISE using Windows Server CA and replace ISE's self-signed certificate with the new certificate but authentication still failed with the same error message. Must I generate a certificate for WLC also? Please help me in solving this problem.
Regards,
Ratna

Certificate-Based User Authentication via Supplicant Failing
Symptoms or
Issue
User authentication is failing on the client machine, and the user is receiving a
“RADIUS Access-Reject” form of message.
Conditions (This issue occurs with authentication protocols that require certificate validation.)
Possible Authentications report failure reasons:
• “Authentication failed: 11514 Unexpectedly received empty TLS message;
treating as a rejection by the client”
• “Authentication failed: 12153 EAP-FAST failed SSL/TLS handshake because
the client rejected the Cisco ISE local-certificate”
Click the magnifying glass icon from Authentications to display the following output
in the Authentication Report:
• 12305 Prepared EAP-Request with another PEAP challenge
• 11006 Returned RADIUS Access-Challenge
• 11001 Received RADIUS Access-Request
• 11018 RADIUS is reusing an existing session
• 12304 Extracted EAP-Response containing PEAP challenge-response
• 11514 Unexpectedly received empty TLS message; treating as a rejection by the
client
• 12512 Treat the unexpected TLS acknowledge message as a rejection from the
client
• 11504 Prepared EAP-Failure
• 11003 Returned RADIUS Access-Reject
• 11006 Returned RADIUS Access-Challenge
• 11001 Received RADIUS Access-Request
• 11018 RADIUS is re-using an existing session
• 12104 Extracted EAP-Response containing EAP-FAST challenge-response
• 12815 Extracted TLS Alert message
• 12153 EAP-FAST failed SSL/TLS handshake because the client rejected the
Cisco ISE local-certificate
• 11504 Prepared EAP-Failure
• 11003 Returned RADIUS Access-Reject
Note This is an indication that the client does not have or does not trust the Cisco
ISE certificates.
Possible Causes The supplicant or client machine is not accepting the certificate from Cisco ISE.
The client machine is configured to validate the server certificate, but is not
configured to trust the Cisco ISE certificate.
Resolution The client machine must accept the Cisco ISE certificate to enable authentication.
