Smart card login to freeipa

[Stephen Berg (Contractor)]

Working on standing up a freeipa server running on SciLinux 7.2.  On a 
Fedora 23 system the smart card is working and authentication works at 
the console.  But trying to log in to a gnome-shell session through gdm 
the smart cards does not authenticate.

Is there a gdm setting somewhere to tell it to authenticate with the 
smart card against the freeipa server like the console login does?
