Smart SAP Assistant

• What is the cause and solution for SAP error message SEFS_LDAP_MSG009 - LDAP is not alive (server &1) ?

  The SAP error message SEFS_LDAP_MSG009 indicates that the LDAP (Lightweight Directory Access Protocol) server is not reachable or not functioning properly. This can occur for various reasons, and understanding the cause is essential for troubleshooting and resolving the issue.
  Causes:
  
  Network Issues: There may be network connectivity problems between the SAP system and the LDAP server. This could be due to firewall settings, routing issues, or network outages.
  LDAP Server Down: The LDAP server itself may be down or not responding. This could be due to server maintenance, crashes, or resource exhaustion.
  Configuration Errors: Incorrect configuration settings in the SAP system for the LDAP connection (e.g., wrong server address, port number, or authentication details).
  DNS Resolution Issues: If the LDAP server is referenced by a hostname, there may be DNS resolution issues preventing the SAP system from finding the LDAP server.
  SSL/TLS Issues: If the connection to the LDAP server is secured using SSL/TLS, there may be issues with certificates or encryption settings.
  
  Solutions:
  
  
  Check Network Connectivity:
  
  Use tools like ping or telnet to check if the LDAP server is reachable from the SAP server.
  Verify firewall settings to ensure that the necessary ports (usually 389 for LDAP and 636 for LDAPS) are open.
  
  
  
  Verify LDAP Server Status:
  
  Check the status of the LDAP server to ensure it is running and accepting connections.
  Review server logs for any errors or issues that may indicate why it is not responding.
  
  
  
  Review Configuration Settings:
  
  In the SAP system, check the LDAP configuration settings (transaction code LDAP or SU01 for user settings) to ensure that the server address, port, and authentication details are correct.
  Ensure that the LDAP server is configured to allow connections from the SAP system.
  
  
  
  DNS Configuration:
  
  If using a hostname for the LDAP server, verify that the hostname resolves correctly to the correct IP address.
  You can use the nslookup or dig command to check DNS resolution.
  
  
  
  SSL/TLS Configuration:
  
  If using LDAPS, ensure that the SSL certificates are valid and properly configured.
  Check the SAP system's trust store to ensure that the LDAP server's certificate is trusted.
  
  
  
  Restart Services:
  
  If the LDAP server is down, restarting the LDAP service may resolve the issue.
  In some cases, restarting the SAP system may also help if there are lingering connection issues.
  
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes related to LDAP integration for any known issues or patches that may address the problem.
  Logs: Review the SAP system logs (transaction SM21) and the LDAP server logs for any additional error messages that could provide more context.
  Documentation: Refer to the SAP documentation for LDAP integration for detailed configuration steps and troubleshooting tips.
  
  By following these steps, you should be able to identify the cause of the SEFS_LDAP_MSG009 error and implement a solution to restore connectivity to the LDAP server.
