Greetings, Currently I am working on "migrating" our radius proxy server from radsecproxy to freeradius 3.0.15 with radsec. At the client side, majority of them are using radsecproxy+freeradius 2.2.9. Connection from the radius proxy via radius port (1812)/non-radsec works well. However, if we change the connection from the radius proxy via radsec it doesn't work. Below is the error message from the proxy server's log (full debug log attached): (1) eap: ERROR: rlm_eap (EAP): No EAP session matching state 0xcacb836ecaca9624 (1) eap: Either EAP-request timed out OR EAP-response to an unknown EAP-request (1) eap: Failed to get handler, probably already removed, not inserting EAP-Failure , while at the client side (full debug log attached): rlm_eap: No EAP session matching the State variable. [eap] Either EAP-request timed out OR EAP-response to an unknown EAP-request [eap] Failed in handler ++[eap] = invalid +} # group authenticate = invalid I used eapol_test to test the authentication. I there anyone faced similar problem before? if yes, would you mind to share the solution? Regards -- *Muhammad Farhan SJAUGI, S.Kom.
