各位好，請教一下，
想嘗試透過 freeradius 結合 eap-tls 的驗證機制，
透過 google 大神有找到一篇類似的設定說明
https://www.tp-link.com/us/support/faq/3456/
照著設定以後，freeradius server 雖然沒有跳 錯誤訊息，
但 windows client 並沒有認證成功
在 switch 上面也只有看到 radius access-challenge packets
不知是否有除錯的方向可以參考，
謝謝大家的回覆。

補充說明：在 freeradius 上開啟 debug mode 後，有發現下列的 error message
(80) eap: ERROR: rlm_eap (EAP): No EAP session matching state
(80) eap: Either EAP-request timed out OR EAP-response to an unknown EAP-request
(80) eap: Failed in handler
(80) [eap] = invalid
(80) } # authenticate = invalid
(80) Failed to authenticate the user
