TRUST099
- Invalid Distinguished Name ?The SAP error message TRUST099: Invalid Distinguished Name typically occurs in the context of SAP systems when dealing with digital certificates, particularly in scenarios involving Secure Network Communications (SNC) or when configuring trust relationships between systems.
Cause:
The error message indicates that there is an issue with the Distinguished Name (DN) format in the certificate being used. This can happen due to several reasons:
- Incorrect Format: The DN may not conform to the expected format, which usually follows the X.500 standard.
- Missing Attributes: Required attributes in the DN (like CN, OU, O, etc.) may be missing.
- Invalid Characters: The DN may contain invalid characters or syntax errors.
- Certificate Issues: The certificate itself may be corrupted or improperly generated.
- Configuration Errors: There may be misconfigurations in the SNC or trust settings in the SAP system.
Solution:
To resolve the TRUST099 error, you can follow these steps:
Check the Distinguished Name:
- Verify the DN format in the certificate. It should look something like this:
CN=CommonName, OU=OrganizationalUnit, O=Organization, L=Locality, ST=State, C=Country
- Ensure that all required components are present and correctly formatted.
Validate the Certificate:
- Use tools like OpenSSL to check the validity of the certificate. You can run commands to inspect the certificate and ensure it is correctly formatted.
- Example command:
openssl x509 -in your_certificate.crt -text -noout
Check for Invalid Characters:
- Ensure that the DN does not contain any invalid characters or spaces that could cause parsing issues.
Review SNC Configuration:
- If you are using SNC, check the SNC parameters in the SAP system (e.g.,
snc/identity/as
andsnc/identity/client
).- Ensure that the SNC library is correctly configured and that the paths to the certificates are correct.
Regenerate Certificates:
- If the certificate is found to be invalid or corrupted, consider regenerating it using a proper Certificate Authority (CA) or self-signing it with the correct parameters.
Consult SAP Notes:
- Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
