• What is the cause and solution for SAP error message TRUST143 - Local PSE has incorrect file mode ?

  The SAP error message TRUST143 indicates that the Local Personal Security Environment (PSE) has an incorrect file mode. This typically means that the permissions set on the PSE file do not meet the security requirements expected by the SAP system.
  Cause:
  The Local PSE is a file that contains security certificates and keys used for secure communication in SAP systems. The error occurs when the file permissions are too permissive, which can pose a security risk. For example, if the PSE file is readable or writable by users other than the intended owner (usually the user running the SAP instance), the system will raise this error.
  Solution:
  To resolve the TRUST143 error, you need to adjust the file permissions of the Local PSE. Here are the steps to do this:
  
  
  Identify the PSE File Location:
  
  The Local PSE is typically located in the directory specified by the profile parameter ssl/identity/as or ssl/client/identity. You can find the exact path by checking the instance profile or using transaction RZ10.
  
  
  
  Change File Permissions:
  
  Navigate to the directory where the PSE file is located. The file is usually named pse or similar.
  Use the command line to change the file permissions. The recommended permissions for the PSE file are:
  
  Owner: Read and Write (rw)
  Group: No permissions (---)
  Others: No permissions (---)
  
  
  You can set these permissions using the following command (replace pse with the actual file name):
  chmod 600 <path_to_pse_file>/pse
  
  
  
  
  Verify Ownership:
  
  Ensure that the PSE file is owned by the user that runs the SAP instance. You can change the ownership using the chown command:
  chown <sap_user>:<sap_group> <path_to_pse_file>/pse
  
  
  
  
  Restart the SAP Instance:
  
  After making the changes, restart the SAP instance to ensure that the changes take effect.
  
  
  
  Related Information:
