E PDM and Microsoft Lync

Apprently in 2013 Epdm you can have the user information pop up use Microsoft Lync (according to the whats new).  how do you enable this functionality?  A peruse of the admin tool doesn't give any clues.   Our vault users are defined using Active Directory user information.

thanks for any clues.

Daniel
