    Hello,

    Is there a tutorial or document that subscribes the bast practice how to configure clearpass to connect Corporate owned iOs and Android devices to our Wireless netwerk via EAP-TLS (Certificate - 802.1x).

    We don't want to use the onboarding service because these devices are not BYOD devices.

    Do you guys have an internal PKI issuing certificates?
    Are these mobiles devices managed via a MDM solution ?

    Yes wa have our own PKI infrastructure and we have a MDM infrastructure. But the problem/clarification we have is on the clearpass side.

    Since you already have an MDM solution in place , you can configure your MDM solution to request a certificate against your PKI on behalf of the device (this will be the best approach)
    What is your concern on the ClearPass side ?

    The certificate is Ok via MDM but how does the service in clearpass needsto be configured?

    EAP-TLS offcours but authentication source??? Since those tablets are no member of our AD what do you chase then?

    You can use clearpass local source
    And create a policy based on the certificate attributes

    When I chose Local Database as authentication I get the follwoing :

    Alerts for this Request 
    RADIUS [Local User Repository] - localhost: User not found.
    EAP-TLS: Authentication failure, unknown user

    Make sure to disable authorization required under the TLS authentication type

    Apperntly the config below did the trick (on MDM side)

    On the MDM side, the WiFi configuration required all of the names on the certificate including CN and ALL SANS, which apparently sounds like an iOS requirement.
