Smart SAP Assistant

• What is the cause and solution for SAP error message SLDAP_ICM023 - Directory service "&1" send referral despite use of ManageDsaIT control ?

  The SAP error message SLDAP_ICM023 indicates that the LDAP (Lightweight Directory Access Protocol) server is sending a referral to another directory service, even though the ManageDsaIT control is being used. This can occur when the LDAP server is configured to refer certain queries to other directory services, which can lead to issues in retrieving the expected data.
  Cause:
  
  Referral Configuration: The LDAP server may be configured to send referrals for certain queries. This can happen if the requested object is not found in the current directory service, and the server is set to refer the request to another directory service.
  ManageDsaIT Control: The ManageDsaIT control is intended to prevent referrals by allowing the client to request that the server not return referrals for certain operations. However, if the LDAP server does not support this control or if it is not implemented correctly, referrals may still be sent.
  LDAP Server Limitations: Some LDAP servers may not fully support the ManageDsaIT control or may have specific configurations that override its effects.
  
  Solution:
  
  Check LDAP Server Configuration: Review the configuration of the LDAP server to ensure that it is set up correctly and that referrals are not being sent unnecessarily. This may involve checking the directory structure and ensuring that the requested objects exist in the directory.
  Verify ManageDsaIT Support: Ensure that the LDAP server supports the ManageDsaIT control. If it does not, you may need to consider alternative approaches to handle referrals.
  Modify Query: If possible, modify the query to ensure that it targets the correct directory service or object. This may involve specifying a different base DN (Distinguished Name) or adjusting the search parameters.
  Consult Documentation: Refer to the documentation for both the SAP system and the LDAP server to understand how referrals are handled and what configurations may be necessary to prevent them.
  Contact Support: If the issue persists, consider reaching out to SAP support or the support team for the LDAP server for further assistance. They may have specific insights or patches that can resolve the issue.
  
  Related Information:
  
  LDAP Basics: Understanding how LDAP works, including its directory structure, object classes, and attributes, can help in troubleshooting issues related to referrals.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error message or provide guidance on LDAP integration.
  Logs and Traces: Review the logs and traces from both the SAP system and the LDAP server to gather more information about the requests being made and the responses being received.
  
  By following these steps, you should be able to diagnose and resolve the issue related to the SLDAP_ICM023 error message.
