• What is the cause and solution for SAP error message SAML2076 - Authentication failed: No appropriate entry in USREXTID ?

  The SAP error message SAML2076: Authentication failed: No appropriate entry in USREXTID typically occurs during the Single Sign-On (SSO) process when the system is unable to find a corresponding entry in the user external ID table (USREXTID) for the user attempting to authenticate. This can happen in scenarios where SAML (Security Assertion Markup Language) is used for authentication.
  
  Cause:
  
  Missing User Mapping: The user trying to log in does not have a corresponding entry in the USREXTID table. This table is used to map external identities (like those from an Identity Provider) to SAP user IDs.
  Incorrect Configuration: The SAML configuration might not be set up correctly, leading to mismatches between the external identity and the SAP user.
  User Not Created: The user may not exist in the SAP system at all, or the user ID may be incorrect.
  Identity Provider Issues: The Identity Provider (IdP) may not be sending the correct attributes or claims
