  • What is the cause and solution for SAP error message 00143 - Issuer of SSO ticket is not authorized ?

    The SAP error message "00143 Issuer of SSO ticket is not authorized" typically occurs in the context of Single Sign-On (SSO) configurations. This error indicates that the system is unable to validate the SSO ticket because the issuer of the ticket is not recognized or authorized by the SAP system.

    Causes:

    1. Incorrect Configuration: The SSO configuration in the SAP system may not be set up correctly. This includes issues with the trust relationship between the SAP system and the identity provider (IdP).
    2. Missing or Incorrect Certificate: The public key certificate of the IdP may not be correctly imported into the SAP system, or it may be outdated.
    3. Wrong Issuer Name: The issuer name in the SSO ticket does not match the expected issuer name configured in the SAP system.
    4. Network Issues: There may be network issues preventing the SAP system from reaching the IdP to validate the ticket.
    5. Expired Ticket: The SSO ticket may have expired, leading to validation failure.

    Solutions:

    1. Check Configuration: Review the SSO configuration in the SAP system. Ensure that the settings for the IdP are correct, including the issuer name and endpoint URLs.
    2. Import Certificate: Ensure that the public key certificate of the IdP is correctly imported into the SAP system. You can do this using transaction code STRUST.
    3. Verify Issuer Name: Check the issuer name in the SSO ticket and ensure it matches the expected issuer name configured in the SAP system.
    4. Network Connectivity: Ensure that there are no network issues preventing communication between the SAP system and the IdP.
    5. Check Ticket Validity: Verify that the SSO ticket is still valid and has not expired. If it has expired, a new ticket should be generated.

    Related Information:

    • Transaction Codes: Use transaction codes like STRUST (for managing SSL certificates) and SSO2 (for SSO configuration) to troubleshoot and configure SSO settings.
    • Logs: Check the SAP system logs (transaction SM21) and the security audit logs for more detailed error messages that can provide additional context.
    • Documentation: Refer to SAP's official documentation on SSO configuration for detailed steps and best practices.
    • Support: If the issue persists, consider reaching out to SAP support or your organization's IT department for further assistance.

SAP messages fall into 3 different categories: Error messages (message type = E), Warnings (W) or Informational (I) messages.

An error message will prevent you from continuing your work - it is a hard stop and you need to fix the error before you can proceed. A warning message will stop your work, however, you can then bypass the warning by pressing the Enter key on your keyboard. That said, it is still good practice to investigate the cause of the warning message and address it. An information message will not stop your work and is truly just for informational purposes.
