Problem
Connections from SB2BI as the client using HTTP with SSL to a SSO server are failing with an error message from the server.
Symptom
- Enhanced SSL logging shows "Error: None of client suites is enabled on server or ECC ciphersuite curve and/or pointformat does not match."
- After the above, enhanced SSL logging shows
"ALERT
Severity Level: FATAL
Alert Type: 40
HANDSHAKE_FAILURE - The handshake handler was unable to negotiate an acceptable set of security parameters." - TCP captures show that Client does not send a certificate in the Client Certificate step
- TCP captures show server sending a fatal alert message of "Handshake Failure" after both sides have sent their Certificate messages and client has sent "Client Key Exchange", "Change Cipher Suite" and an "Encrypted Handshake Message".
