• What is the cause and solution for SAP error message SAML2010 - Identity federation of user &1 (format: &2) failed ?

  The SAP error message SAML2010 indicates that there was a failure in the identity federation process for a user. This typically occurs in scenarios where SAP systems are integrated with external identity providers (IdPs) using SAML (Security Assertion Markup Language) for Single Sign-On (SSO) purposes.
  Cause
  The error message can be caused by several factors, including:
  
  
  Incorrect User Mapping: The user in the SAP system does not match the user in the identity provider. This could be due to differences in usernames, email addresses, or other identifiers.
  
  
  Configuration Issues: There may be misconfigurations in the SAML settings, such as incorrect entity IDs, assertion consumer service URLs, or certificate issues.
  
  
  Expired or Invalid Tokens: The SAML assertion (token) provided by the IdP may be expired or invalid.
  
  
  Network Issues: There could be connectivity issues between the SAP system and the identity provider.
  
  
  Missing Attributes: Required attributes in the SAML assertion may be missing or not correctly mapped to the SAP user profile.
  
  
  Solution
  To resolve the SAML2010 error, you can follow these steps:
  
  
  Check User Mapping:
  
  Ensure that the user in the SAP system corresponds correctly to the user in the identity provider. Verify that the identifiers (e.g., usernames, email addresses) match.
  
  
  
  Review SAML Configuration:
  
  Check the SAML configuration settings in the SAP system. Ensure that the entity IDs, assertion consumer service URLs, and certificates are correctly configured.
  
  
  
  Validate SAML Assertion:
  
  Use tools like SAML Tracer or browser developer tools to inspect the SAML assertion being sent from the IdP. Check for expiration and ensure that all required attributes are present.
  
  
  
  Check Network Connectivity:
  
  Ensure that there are no network issues preventing the SAP system from communicating with the identity provider.
  
  
  
  Consult Logs:
  
  Review the SAP system logs (transaction codes like SLG1) for more detailed error messages that can provide additional context on the failure.
  
  
  
  Test with Different Users:
  
  If possible, test the SSO process with different users to determine if the issue is user-specific or a broader configuration issue.
  
  
  
  Update Certificates:
  
  If you are using certificates for signing or encryption, ensure that they are up to date and correctly configured.
