SAP Error Message - Details

• Message type: E = Error

• Message class: LDAPSYNC - Messages for Synchronization with a Directory

• Message number: 018

• Message text: Found a directory object more than once: &3 (&4)

What causes this issue?

When determining the directory entries, which are used for
synchronization, at least two entries were found under the Basis DN
entered for the server in which the filter attribute entered in the
mapping has the same value.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

Two of these entries have the following Distinguished Names:
&V1&
&V2&

System Response

The obejcts to be synchronized must be unique in the filter attributes.
The current situation therefore does not permit synchronization.

How to fix this error?

Check the structure of the objects to be synchronized in the directory.
The attribute used as the filter attribute must be unique across all
objects under the Basis DN.

  Check LDAP Configuration:
  
  Review the LDAP configuration settings in SAP to ensure that the mappings and search filters are correctly defined. Make sure that the synchronization process is set up to handle unique entries properly.
  
  
  
  Data Cleanup:
  
  Perform a data cleanup in the LDAP directory to ensure that there are no inconsistencies or duplicates. This may involve working with the LDAP administrator to enforce data integrity rules.
