  • What is the cause and solution for SAP error message SLDAP_ICM013 - STARTTLS negotiation with directory service "&1" results in error &2&3&4 ?

    The SAP error message SLDAP_ICM013 indicates that there is an issue with the STARTTLS negotiation when trying to establish a secure connection with a directory service (like LDAP). This error typically arises when the SAP system is attempting to communicate with an LDAP server using the STARTTLS command, which is used to upgrade an unencrypted connection to a secure one.

    Causes:

    1. Incorrect LDAP Configuration: The LDAP server settings in the SAP system may be incorrect, including the server address, port, or security settings.
    2. TLS/SSL Certificate Issues: The SSL/TLS certificates used for the connection may be invalid, expired, or not trusted by the SAP system.
    3. Firewall or Network Issues: A firewall or network configuration may be blocking the connection or the STARTTLS command.
    4. LDAP Server Configuration: The LDAP server may not be configured to support STARTTLS or may have issues that prevent it from accepting secure connections.
    5. Version Mismatch: There may be a mismatch in the supported TLS versions between the SAP system and the LDAP server.

    Solutions:

    1. Check LDAP Configuration:

      • Verify the LDAP server settings in the SAP system (transaction code LDAP).
      • Ensure that the server address, port, and other parameters are correctly configured.
    2. Validate Certificates:

      • Check the SSL/TLS certificates used by the LDAP server.
      • Ensure that the certificates are valid, not expired, and trusted by the SAP system.
      • If necessary, import the LDAP server's certificate into the SAP system's trust store.
    3. Network and Firewall Settings:

      • Ensure that there are no firewalls or network policies blocking the connection to the LDAP server.
      • Test connectivity to the LDAP server using tools like telnet or openssl to ensure that the port is open and reachable.
    4. LDAP Server Configuration:

      • Check the configuration of the LDAP server to ensure that it supports STARTTLS.
      • Review the server logs for any errors or warnings that may indicate issues with the STARTTLS negotiation.
    5. TLS Version Compatibility:

      • Ensure that both the SAP system and the LDAP server support compatible versions of TLS.
      • If necessary, adjust the TLS settings on either side to ensure compatibility.

    Related Information:

    • SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
    • Logs: Review the SAP system logs (transaction SM21) and the LDAP server logs for more detailed error messages that can provide insight into the issue.
    • Documentation: Refer to the SAP documentation for LDAP integration and security settings for more detailed guidance on configuring LDAP connections.

    By following these steps, you should be able to diagnose and resolve the SLDAP_ICM013 error in your SAP system.
