Overview
The <ReturnAttributes>
 element contains a whitespace-delimited list of attributes to be returned from the LDAP directory, to optimize the lookup. It carries no attribute or child element content.
Examples
<ReturnAttributes>ATTRIBUTE_1 ATTRIBUTE_2 ATTRIBUTE_3</ReturnAttributes>
On OpenLDAP directory servers, operational attributes must be explicitly requested for them to be returned. If you'd like to return all attributes ( * )Â from an OpenLDAP directory, and the operational attributes ( + ), use the following:
<ReturnAttributes>* +</ReturnAttributes>
