ClearPass Error 215

  • 1.  ClearPass Error 215

    Posted Apr 20, 2017 04:00 PM

    A workstation was joined to the domain. It was ypgraded from Win 7 to Win 10 and now ClearPass gives me this error: 

    EAP-PEAP: fatal alert by client - unknown_ca
    eap-tls: Error in establishing TLS session

    802.1x is configured on the switchport.

    I'm thinking something changed because of the upgrade and now ClearPass won't authenticate because it thinks it's a different workstation?

    I removed aaa config off port, bounced it, then reapplied aaa config. 

    ClearPass still won't authenticate it? 

    Any suggestions?

    Is your EAP server certificate public or privately signed?

     

    Are your supplicants configured via group policy or manually?

    I removed the computer from the domain, deleted the computer account in AD, then rejoined the domain and everything came up smoothly. 

     

    Case Closed!!!
