Hi, I am new to freeradius and hope someone here can help me with my setup. Thanks a lot! Here is what i got when running radiusd with -X option: (8) suffix: Checking for suffix after "@" (8) suffix: No '@' in User-Name = "testing", looking up realm NULL (8) suffix: No such realm "NULL" (8) [suffix] = noop (8) eap: Peer sent EAP Response (code 2) ID 2 length 66 (8) eap: No EAP Start, assuming it's an on-going EAP conversation (8) [eap] = updated (8) } # authorize = updated (8) Found Auth-Type = eap (8) # Executing group from file /etc/raddb/sites-enabled/default (8) authenticate { (8) eap: Expiring EAP session with state 0x065c081f075e1207 (8) eap: Finished EAP session with state 0x065c081f075e1207 (8) eap: Previous EAP request found for state 0x065c081f075e1207, released from the list (8) eap: Peer sent packet with method EAP MSCHAPv2 (26) (8) eap: Calling submodule eap_mschapv2 to process data (8) eap_mschapv2: # Executing group from file /etc/raddb/sites-enabled/default (8) eap_mschapv2: authenticate { (8) mschap: WARNING: No Cleartext-Password configured. Cannot create NT-Password (8) mschap: Creating challenge hash with username: testing (8) mschap: Client is using MS-CHAPv2 (8) mschap: ERROR: FAILED: No NT/LM-Password. Cannot perform authentication (8) mschap: ERROR: MS-CHAP2-Response is incorrect (8) eap_mschapv2: [mschap] = reject (8) eap_mschapv2: } # authenticate = reject (8) eap: Sending EAP Failure (code 4) ID 2 length 4 (8) eap: Freeing handler (8) [eap] = reject (8) } # authenticate = reject (8) Failed to authenticate the user If i run: radtest -t mschap ..., everything seems fine and it output 'Received Access-Accept'. I guess its because the radtest is running with mschap, and my client above is using mschapv2. I can't figure out what config i should do with mschapv2. The radius is running with mysql. user and password are insert to with sql: INSERT INTO `radcheck` VALUES (2,'testing','Cleartext-Password',':=','testuser_mypass'); Thanks a lot!
