I am adding a category in refinment panel which maps to a managed property of type People Group. It works fine except it displays login name of the user instead of display name. I need to display name like "Alex Wong" not like "domainname\loginname".
In the refinement panel schema I am using type as "ManagedPropertyFilterGenerator" and using managed property name as "Mapped Property".
Please let me know if you have any idea about how can I display username here.
I checked category name 'Author' in OOB webpart but there 'Author' column type is single line of text not people and group.
