• What is the cause and solution for SAP error message SAML2100 - Signature algorithm '&1' is out of the required hash algorithms: &2 ?

  The SAP error message SAML2100 indicates that there is an issue with the signature algorithm being used in a SAML (Security Assertion Markup Language) authentication process. Specifically, the error states that the signature algorithm specified (denoted as &1) is not among the required hash algorithms (denoted as &2) that are supported or expected by the system.
  
  Cause:
  This error typically arises due to one of the following reasons:
  
  Incompatible Signature Algorithm: The signature algorithm being used in the SAML assertion does not match the algorithms that are configured or supported in the SAP system.
  Configuration Mismatch: There may be a mismatch in the configuration settings between the Identity Provider (IdP) and the Service Provider (SP) in terms of the supported signature algorithms.
  Outdated or Unsupported Algorithms: The algorithm being used may be outdated or not considered secure by the current standards, leading to it being rejected by the SAP system.
  
  
  Solution:
  To resolve the SAML2100 error, you
