Full Name and Dept - SSL VPN Report

Afternoon all,

I am trying, if possible, to create a SSL VPN report that has not only the ad username but also the real name and dept of the employee.  I have created a custom report that shows all the vpn logins for the past day as per the attached screenshot and just need to flesh out the columns if i can.  I have added our AD server into the Fortianalyser but dont know how to add the fields in for what i want.  Any help would be great.
