• What is the cause and solution for SAP error message STRUSTCR057 - The critical CRL extension "Issuing Distribution Point" is not supported ?

  The SAP error message STRUSTCR057 indicates that there is an issue with the Certificate Revocation List (CRL) related to the "Issuing Distribution Point" (IDP) extension. This error typically arises when the CRL being used does not support the IDP extension, which is required for the validation of certain certificates.
  Cause:
  
  CRL Format: The CRL being used may not be in a format that supports the IDP extension. This can happen if the CRL is generated by a Certificate Authority (CA) that does not include this extension.
  Certificate Configuration: The certificates being validated may require the IDP extension for proper revocation checking, and if the CRL does not support it, the validation will fail.
  SAP Trust Configuration: The configuration in the SAP system regarding trust relationships and certificate validation may not be set up correctly.
  
  Solution:
  
  Update CRL: Obtain a new CRL from the Certificate Authority that includes the IDP extension. Ensure that the CRL is up-to-date and correctly configured.
  Check CA Configuration: If you are managing your own CA, ensure that the CRL generation settings include the IDP extension. You may need to adjust the CA's configuration to include this extension in the CRL.
  SAP Trust Configuration:
  
  Go to transaction STRUST in your SAP system.
  Check the SSL server/client PSE (Personal Security Environment) and ensure that the correct certificates and CRLs are being used.
  Import the updated CRL into the appropriate PSE.
  
  
  Testing: After updating the CRL and ensuring the configuration is correct, test the connection or operation that was previously failing to confirm that the issue is resolved.
  
  Related Information:
  
  SAP Documentation: Refer to SAP's official documentation for STRUST and CRL management for detailed steps on managing certificates and CRLs.
  Certificate Authority: If you are using a third-party CA, consult their documentation or support for guidance on obtaining a CRL that includes the IDP extension.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
