SAML2018
- No user found for name ID '&1' (format: persistent, type: out-of-band) ?The SAP error message SAML2018 indicates that the system could not find a user corresponding to the provided Name ID in a SAML (Security Assertion Markup Language) authentication process. This typically occurs in scenarios where Single Sign-On (SSO) is implemented using SAML.
Cause:
- User Not Provisioned: The user with the specified Name ID does not exist in the SAP system. This could be due to a lack of user provisioning or synchronization issues between the identity provider (IdP) and the service provider (SP).
- Incorrect Name ID Format: The Name ID format being used may not match what the SAP system expects. The error message indicates that the format is "persistent" and the type is "out-of-band," which may not be correctly configured.
- Configuration Issues: There may be misconfigurations in the SAML settings, such as incorrect mappings between the IdP and the SP.
- User Deactivation: The user may have been deactivated or deleted in the SAP system.
Solution:
- User Provisioning: Ensure that the user exists in the SAP system. If the user is supposed to be created automatically via SAML, check the provisioning process from the IdP to the SAP system.
- Check Name ID Configuration: Verify that the Name ID format and type being sent by the IdP matches what the SAP system is configured to accept. This includes checking the SAML assertion settings in the IdP.
- User Activation: If the user exists but is inactive, reactivate the user in the SAP system.
- Review SAML Configuration: Check the SAML configuration in both the IdP and the SAP system. Ensure that the user attributes are correctly mapped and that the SAML settings are properly configured.
- Logs and Traces: Review the logs on both the IdP and the SAP system for any additional error messages or warnings that could provide more context about the issue.
