• What is the cause and solution for SAP error message SAML2183 - No email found for User '&1' ?

  The SAP error message SAML2183, which states "No email found for User '&1'", typically occurs in the context of Single Sign-On (SSO) configurations, particularly when using SAML (Security Assertion Markup Language) for authentication. This error indicates that the system is unable to find an email address associated with the specified user, which is often required for SSO processes, such as sending notifications or for identity assertions.
  Cause:
  
  Missing Email Address: The most common cause is that the user profile in the SAP system does not have an email address assigned.
  User Not Properly Configured: The user may not be properly configured in the identity provider (IdP) or service provider (SP) settings.
  SAML Configuration Issues: There may be issues with the SAML configuration that prevent the email attribute from being correctly mapped or retrieved.
  User Not Active: The user account may be inactive or locked, which can also lead to this error.
  
  Solution:
  
  
  Check User Profile:
  
  Go to the user management transaction (e.g., SU01) in SAP.
  Enter the user ID that is causing the error and check the "Address" tab to ensure that an email address is filled in.
  If it is missing, add a valid email address and save the changes.
  
  
  
  Verify SAML Configuration:
  
  Check the SAML configuration in both the SAP system and the identity provider.
  Ensure that the email attribute is correctly mapped in the SAML assertion. This may involve checking the attribute mappings in the IdP configuration.
  
  
  
  User Activation:
  
  Ensure that the user account is active and not locked. You can check this in the user management transaction (SU01) as well.
  
  
  
  Testing:
  
  After making the necessary changes, test the SSO login process again to see if the error persists.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or the specific SAML configuration guide for your version of SAP to ensure that all settings are correctly configured.
  
  
  
  Related Information:
  
  SAML Assertions: Understand how SAML assertions work and what attributes are typically included.
  User Management: Familiarize yourself with user management transactions in SAP, such as SU01, SU10, and SUIM.
  Identity Provider Documentation: Review the documentation for the identity provider you are using to ensure that it is configured correctly to send the necessary attributes.
