SAML2102
- Signing certificate of the SOAP message is not trusted ?The SAP error message SAML2102 indicates that the signing certificate of the SOAP message is not trusted. This typically occurs in scenarios involving SAML (Security Assertion Markup Language) authentication, where a SOAP message is signed with a certificate that the SAP system does not recognize as valid or trusted.
Cause
The error can be caused by several factors:
- Untrusted Certificate: The signing certificate used in the SOAP message is not present in the trusted certificate store of the SAP system.
- Expired Certificate: The certificate may have expired, making it invalid for use.
- Incorrect Configuration: The configuration for the SAML or SOAP service may not be set up correctly, leading to trust issues.
- Certificate Chain Issues: If the signing certificate is part of a chain, intermediate certificates may not be trusted or installed.
Solution
To resolve the SAML2102 error, follow these steps:
Import the Signing Certificate:
- Obtain the signing certificate from the service provider (the entity sending the SOAP message).
- Import the certificate into the SAP system's trust store. This can typically be done using transaction STRUST.
- Go to STRUST.
- Select the appropriate PSE (Personal Security Environment) for your scenario (e.g., SSL Client (Anonymous), SSL Client (Standard), etc.).
- Click on "Import Certificate" and upload the signing certificate.
- Save your changes.
Check Certificate Validity:
- Ensure that the certificate is not expired. If it is, request a new certificate from the service provider.
Verify Configuration:
- Check the configuration settings for the SAML or SOAP service in your SAP system. Ensure that the endpoint and security settings are correctly configured.
Check Certificate Chain:
- If the signing certificate is part of a chain, ensure that all intermediate certificates are also imported into the trust store.
Restart Services:
- After making changes to the trust store, it may be necessary to restart the relevant services or the entire SAP system to ensure that the changes take effect.
