• What is the cause and solution for SAP error message LDAPACCESS004 - Object Not Unique ?

  The SAP error message LDAPACCESS004 Object Not Unique typically occurs when there is an issue with the LDAP (Lightweight Directory Access Protocol) configuration in SAP systems. This error indicates that the LDAP search operation returned multiple entries for a single object, which is not expected in the context of the operation being performed.
  Cause:
  
  
  Duplicate Entries: The most common cause of this error is that there are multiple entries in the LDAP directory that match the search criteria. For example, if you are trying to retrieve a user by their username or email address, and there are multiple users with the same username or email, the system cannot determine which one to use.
  
  
  Improper Configuration: The LDAP configuration in the SAP system may not be set up correctly, leading to ambiguous search results.
  
  
  Data Integrity Issues: There may be data integrity issues within the LDAP directory itself, such as duplicate records that should be unique.
  
  
  Solution:
  
  
  Check for Duplicates: Use an LDAP browser or command-line tool to search the LDAP directory for the object in question. Look for duplicate entries that match the search criteria. If duplicates are found, you may need to resolve them by either deleting or merging the entries.
  
  
  Refine Search Criteria: Modify the search criteria in the SAP system to be more specific. This can help ensure that the search returns a unique result. For example, if searching by username, consider including additional attributes like the user's organizational unit.
  
  
  Review LDAP Configuration: Check the LDAP configuration settings in the SAP system. Ensure that the base DN (Distinguished Name) and search filters are correctly configured to avoid ambiguous results.
  
  
  Data Cleanup: If the LDAP directory contains duplicate entries, consider performing a cleanup to remove or consolidate these entries. This may involve working with your LDAP administrator.
  
  
  Consult Documentation: Refer to SAP documentation or support resources for specific guidance on configuring LDAP connections and handling errors.
