Linux - Can't connect to University Wifi (WPA enterprise + PEAP + PAP)

I want connect to University Wifi.
I use Debian (and Gnome3)
cat /etc/debian_version
jessie/sid
Settings for Wifi are (they don't use certificates):
Wireless Security: WPA & WPA2 Enterprise
Authentification: PEAP
PEAP version: automatic
Inner Authentification: PAP
I can't find Inner Authentification: PAP options.
How do I install PAP option?
