  • 1.  Smartcard 802.1x EAP-TLS authentication

    Posted 12-20-2018 11:08
    Hello,
    I'm working on smartcard authentication with Yubikey4 [smartcard].
    As far authentication works as intended with one annoying bug I cannot overcome.
    User can log in into domain with yubikey, connect to Extreme wifi [identifi] , and authenticate with smartcard certificate. When yubikey is removed and wifi disconnected, another connection is immpossible till windows user logout and login.


    XMC shows: "Authentication request became stale, challenge sent, no response received from client"
    Any ideas how to fix it ?

    Hi Tomasz,

    the message "Authentication request became stale, challenge sent, no response received from client" usually indicates a config error on the client's supplicant. You could debug this deeper by enabling certain verbose logs on the NAC appliance but for now I would try to play with the Windows Supplicant config where you configured your smart card.

    Thanks Kurt, it looks like disabling "Remember my credentials..." on security wifi tab - helps 🙂
