    Posted Aug 12, 2016 12:19 AM

    Hi All,

    I tried to do machine + user authentication with EAP-TLS as authentication method.

    But when doing machine authentication, its getting timeout and showing below error in CPPM,

    Error Code: 9002
    Error Category: RADIUS protocol
    Error Message: Request timed out
    Alerts for this Request
    RADIUS Request Timed out

     

    And after failing to do machine authentication the same machine is  doing user authentication. Which is working as expected.

    Wired or wireless?
    What vendor?
    Who is issuing the certificates?
    What version of Windows?
    Is the supplicant configured through group policy?

    Its wired.

    Client is windows machine & the switch is Cisco.

    CA is issuing certificate.

    Windows 7.

    I guess supplicant is configured through group policy.

    9002 and a timeout can be because a client is asked to trust a server certificate, but does not.  Has this ever worked?  There is quite a bit of work to get EAP-TLS working.

    Thanks Colin,

    Turned out to be a wrong machine certificate installed on Client machine.

    Changed the certificate and worked :)

    Hello,

     

    I have this same error on my Macbook Pro. I have used this Mac previously on this network but ever since I onboarded and tried to un-board it. I have not been able to join the wifi anymore.

     

    Packet capture shows that Macbook is sending Response, Legacy Nak (Response Only).
