Hello world! Trying to enable EPA2 Enterprise authentication for a Cisco Meraki AP. EAP Authenticaton section fails with the following: ===================================== (2) eap: Peer sent EAP Response (code 2) ID 2 length 161 (2) eap: Continuing tunnel setup (2) [eap] = ok (2) } # authorize = ok (2) Found Auth-Type = eap (2) # Executing group from file /usr/local/etc/raddb/sites-enabled/default (2) authenticate { (2) eap: Expiring EAP session with state 0x1da40b4e1ca6122b (2) eap: Finished EAP session with state 0x1da40b4e1ca6122b (2) eap: Previous EAP request found for state 0x1da40b4e1ca6122b, released from the list (2) eap: Peer sent packet with method EAP PEAP (25) (2) eap: Calling submodule eap_peap to process data (2) eap_peap: Continuing EAP-TLS (2) eap_peap: [eaptls verify] = ok (2) eap_peap: Done initial handshake (2) eap_peap: (other): before/accept initialization (2) eap_peap: TLS_accept: before/accept initialization tls: TLS_accept: Error in SSLv2/v3 read client hello A (2) eap_peap: ERROR: Failed in __FUNCTION__ (SSL_read): error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol (2) eap_peap: ERROR: System call (I/O) error (-1) (2) eap_peap: ERROR: TLS receive handshake failed during operation (2) eap_peap: ERROR: [eaptls process] = fail (2) eap: ERROR: Failed continuing EAP PEAP (25) session. EAP sub-module failed (2) eap: Sending EAP Failure (code 4) ID 2 length 4 (2) eap: Failed in EAP select (2) [eap] = invalid (2) } # authenticate = invalid (2) Failed to authenticate the user ===================================== Any idea where I may need to start troubleshooting? I haven't touched Authentication at all from its original. Authorization is done through python3 and seems to be working just fine. By the way, exactly the same error occurs on a different freeradius server running 3.021 Thank you! Gleb
