• What is the cause and solution for SAP error message LDAPMAP029 - Cannot use binary attribute &1 to create RDN ?

  The SAP error message LDAPMAP029 indicates that there is an issue with using a binary attribute to create a Relative Distinguished Name (RDN) in an LDAP (Lightweight Directory Access Protocol) context. This typically occurs when there is an attempt to use an attribute that is not suitable for RDN creation, as RDNs must be represented in a string format.
  Cause:
  The error is caused by trying to use a binary attribute (such as an attribute that stores data in binary format) as part of the RDN. RDNs are meant to be human-readable and typically consist of string attributes like cn (common name), ou (organizational unit), or uid (user ID). Binary attributes, on the other hand, are not suitable for this purpose because they cannot be represented as strings.
  Solution:
  To resolve this error, you should:
  
  
  Identify the Attribute: Determine which attribute is being used as the RDN that is causing the error. The error message will indicate the specific attribute (represented as &1).
  
  
  Change the RDN Attribute: Modify the configuration to use a valid string attribute for the RDN instead of the binary attribute. This may involve changing the mapping in your LDAP configuration or in the SAP system settings.
  
  
  Check LDAP Schema: Ensure that the LDAP schema you are working with supports the attributes you are trying to use. If necessary, consult the LDAP documentation or schema definitions.
  
  
  Test the Configuration: After making the changes, test the configuration to ensure that the RDN can be created successfully without triggering the error.
  
  
  Related Information:
  
  LDAP RDN: A Relative Distinguished Name is a component of a Distinguished Name (DN) in LDAP. It uniquely identifies an entry within its parent context.
  Binary Attributes: These are attributes that store data in a binary format, such as images or files, and are not suitable for RDNs.
  SAP and LDAP Integration: When integrating SAP with LDAP, it is crucial to ensure that the attribute mappings are correctly configured to avoid such errors.
  
  If you continue to experience issues after following these steps, consider consulting SAP support or your LDAP administrator for further assistance.
