Fetch TER Result Owner Name in RPE-RQM report

Right now , I am able to fetch User ID information for TER Result owner. Since our environment is LDAP configured , and User ID equals Email id..RPE prints the email id's of the TER owner. I would like to fetch the user names. I know the user names are stored in the 'Contributor' element, but not sure how to user it in RPE.



How do I use the contributor and query to fetch User Names ?

Appreciate your help
