  • What is the cause and solution for SAP error message SAML2153 - No PSEs were found in the configuration file. ?

    The SAP error message SAML2153: No PSEs were found in the configuration file typically indicates that the system is unable to find the Personal Security Environment (PSE) files required for Secure Network Communications (SNC) or for handling SAML assertions. This can occur in scenarios where secure communication is necessary, such as when using Single Sign-On (SSO) or when integrating with external identity providers.

    Cause

    The error can be caused by several factors:

    1. Missing PSE Files: The PSE files that are required for the configuration are not present in the expected directory.
    2. Incorrect Configuration: The configuration file may not be correctly set up to point to the location of the PSE files.
    3. Permissions Issues: The user or service account running the SAP application may not have the necessary permissions to access the PSE files.
    4. Corrupted PSE Files: The PSE files may be corrupted or improperly generated.

    Solution

    To resolve the SAML2153 error, you can follow these steps:

    1. Check PSE Files:

      • Verify that the PSE files exist in the expected directory. The default location is usually in the sec directory of the SAP instance (e.g., /usr/sap/<SID>/SYS/global/security).
      • Ensure that the PSE files are correctly named and formatted.
    2. Review Configuration:

      • Check the configuration settings in the SAP system. This includes the SAML2 configuration and any related settings in transaction SAML2.
      • Ensure that the configuration file correctly points to the location of the PSE files.
    3. Permissions:

      • Ensure that the user or service account running the SAP application has the necessary permissions to read the PSE files. You may need to adjust file permissions or ownership.
    4. Generate New PSE:

      • If the PSE files are missing or corrupted, you may need to generate new PSE files. This can be done using the transaction STRUST in the SAP GUI:
        • Go to transaction STRUST.
        • Select the appropriate PSE (e.g., SSL Client PSE or SSL Server PSE).
        • Use the "Create" or "Import" options to generate or import a new PSE.
    5. Restart the SAP System:

      • After making changes, it may be necessary to restart the SAP system or the relevant services to ensure that the changes take effect.
