UserApplication 4.0.1

I have to add few more attributes to the attributes list shown when we
do search for an user object.
Workdashboard --> Manage--> (user)--> Search object list

This show me an option to search with the Firstname & Lastname. If i
want to add few more attributes like CN,Tile based search. How can i add
this? I have some idea that we can achieve this via portlet. But not
sure which portlet i should modify.
