• What is the cause and solution for SAP error message TRUST089 - SSL client &1 ?

  The SAP error message TRUST089 typically indicates an issue with SSL client authentication. The message usually states that the SSL client certificate is not trusted or that there is a problem with the SSL configuration. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Untrusted Certificate: The SSL client certificate being used is not trusted by the server. This can happen if the certificate is self-signed or if the issuing Certificate Authority (CA) is not recognized by the server.
  Missing CA Certificates: The CA certificates that signed the client certificate are not present in the server's trust store.
  Expired Certificate: The client certificate may have expired, making it invalid for authentication.
  Incorrect SSL Configuration: There may be misconfigurations in the SSL settings on either the client or server side.
  
  Solutions:
  
  
  Import the Client Certificate:
  
  Ensure that the client certificate is imported into the server's trust store. You can do this using transaction STRUST in the SAP GUI.
  Navigate to the appropriate SSL client identity and import the certificate.
  
  
  
  Import CA Certificates:
  
  If the client certificate is issued by a CA, ensure that the CA's root and intermediate certificates are imported into the server's trust store.
  Again, use transaction STRUST to manage the certificates.
  
  
  
  Check Certificate Validity:
  
  Verify that the client certificate is still valid and has not expired. If it has expired, you will need to renew it.
  
  
  
  Review SSL Configuration:
  
  Check the SSL configuration settings in the SAP system. Ensure that the SSL parameters are correctly set in the instance profile.
  Ensure that the SSL protocol versions and cipher suites are compatible between the client and server.
  
  
  
  Test SSL Connection:
  
  Use tools like OpenSSL to test the SSL connection and verify that the certificates are correctly set up and trusted.
  
  
  
  Check Logs:
  
  Review the SAP system logs (transaction SM21) and the SSL trace logs for more detailed error messages that can provide additional context.
