NPS reason code 293 - EAP-TLS problem with Cisco IP-Phone RRS feed

  • Question

  • Hi,

    i am currently trying to set up EAP-TLS for Cisco 7841 IP-Phones. I have a RootCA that signed a SubordinateCA certificate for the IP-Phone server. The phones have the certificates signed by this server.

    The NPS server throws an event(6273) with the reason code 293 (The certificate is not valid for the requested usage). Currently i have know idea what to do with this information and i don't know anything else i could troubleshoot. The configuration on switch/nps should be ok, since it works for windows clients wired/wireless.

    Glad for help/ideas!

    Thanks in advance
