• What is the cause and solution for SAP error message SAML2030 - Authentication context &1 is not supported ?

  The SAP error message SAML2030 indicates that the authentication context specified in the SAML (Security Assertion Markup Language) assertion is not supported by the SAP system. This typically occurs during Single Sign-On (SSO) scenarios where the system is trying to authenticate a user based on a SAML assertion, but the context defined in that assertion does not match any of the contexts that the SAP system is configured to accept.
  Causes:
  
  Unsupported Authentication Context: The SAML assertion contains an authentication context that the SAP system does not recognize or support.
  Configuration Issues: The SAML configuration in the SAP system may not be set up to accept the specific authentication context being sent by the Identity Provider (IdP).
  Mismatch Between IdP and SAP: The IdP may be configured to use a different authentication context than what is expected by the SAP system.
  Version Compatibility: There may be compatibility issues between the versions of the IdP and the SAP system regarding supported authentication contexts.
  
  Solutions:
  
  
  Check Supported Authentication Contexts:
  
  Review the authentication contexts that are configured in your SAP system. This can typically be done in the SAML configuration settings.
  Ensure that the authentication context specified in the SAML assertion matches one of the supported contexts in the SAP system.
  
  
  
  Modify IdP Configuration:
  
  If the IdP is sending an unsupported authentication context, you may need to modify its configuration to send a supported context.
  Consult the documentation for your IdP to understand how to configure the authentication context.
  
  
  
  Update SAP Configuration:
  
  If necessary, update the SAP system's SAML configuration to include the required authentication context. This may involve adding new contexts that the IdP is using.
  
  
  
  Testing:
  
  After making changes, perform tests to ensure that the SSO process works correctly and that users can authenticate without encountering the SAML2030 error.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation and the documentation for your IdP for specific instructions on configuring SAML and supported authentication contexts.
  
  
  
  Related Information:
  
  SAML Assertions: Understand the structure of SAML assertions and how authentication contexts are defined.
  SAP SSO Configuration: Familiarize yourself with the steps to configure SSO in SAP, including the setup of SAML and the necessary trust relationships between the SAP system and the IdP.
  Logs and Traces: Check the SAP system logs and traces for additional information that may help diagnose the issue further.
  
  If the problem persists after following these steps, consider reaching out to SAP support or your IdP's support for further assistance.
