Hi,
thanks for the quick answer.
Now, i tried to connect to the server as follow:
ssl:connect(HOST, 636, [{cacertfile, "EquifaxSecureCA.pem"}, {verify, verify_none}]).=ERROR REPORT==== 15-Jan-2013::09:33:14 ===SSL: certify: ssl_handshake.erl:239:Fatal error: certificate unknown{error,"certificate unknown"}
As i understand from your last mail, the client needs a server certificate with the following informations:








Subject: C=US, O=Equifax, OU=Equifax Secure Certificate Authority
	X509v3 Subject Key Identifier:   48:E6:68:F9:2B:D2:B2:95:D7:47:D8:23:20:10:4F:33:98:90:9F:D4
This informations are included in the EquifaxSecureCA.pem which i added as a cacertfile to the connect function,but i got the same result.
Please, can you tell me, what i am doing wrong?
Thanks and best regards,Ulf
