• What is the cause and solution for SAP error message LDAPACCESS012 - Define an RDN attribute in the map ?

  The SAP error message LDAPACCESS012: "Define an RDN attribute in the map" typically occurs when there is an issue with the configuration of the LDAP (Lightweight Directory Access Protocol) mapping in the SAP system. This error indicates that the system is unable to find a suitable RDN (Relative Distinguished Name) attribute in the LDAP mapping configuration.
  Cause:
  The error is usually caused by one of the following reasons:
  
  Missing RDN Attribute: The mapping configuration does not specify an RDN attribute, which is necessary for uniquely identifying entries in the LDAP directory.
  Incorrect Mapping Configuration: The mapping may be incorrectly set up, leading to the system not recognizing the RDN attribute.
  LDAP Schema Issues: The LDAP schema may not have the expected attributes defined, or there may be a mismatch between the SAP system and the LDAP directory.
  
  Solution:
  To resolve the LDAPACCESS012 error, you can follow these steps:
  
  
  Check LDAP Mapping Configuration:
  
  Go to the transaction code LDAP in SAP.
  Review the LDAP mapping configuration to ensure that an RDN attribute is defined. The RDN attribute is typically a unique identifier for the entries, such as cn (common name) or uid (user ID).
  
  
  
  Define an RDN Attribute:
  
  If an RDN attribute is not defined, you need to add it. This can usually be done in the LDAP mapping settings where you specify the attributes for user and group mappings.
  Ensure that the RDN attribute you choose is appropriate for your LDAP directory structure.
  
  
  
  Validate LDAP Schema:
  
  Check the LDAP schema to ensure that the attributes you are trying to map exist and are correctly defined.
  If necessary, consult with your LDAP administrator to verify the schema and attributes.
  
  
  
  Test the Configuration:
  
  After making changes, test the LDAP connection and mapping to ensure that the error is resolved.
  You can use the LDAP test tools available in SAP to verify the connection and mapping.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for LDAP integration for specific details on configuring LDAP mappings and attributes.
  
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes related to LDAP integration for any known issues or additional guidance.
  LDAP Documentation: Review the documentation for your specific LDAP server (e.g., Active Directory, OpenLDAP) for details on RDN attributes and schema.
  SAP Community: Engage with the SAP Community forums for insights from other users who may have encountered similar issues.
  
  By following these steps, you should be able to resolve the LDAPACCESS012 error and successfully configure the LDAP mapping in your SAP system.
