WPA2-Enterprise: PAP not shown in phase 2 auth spinner

I need to setup a 802.1x EAP Wi-Fi network on a JellyBean device (Motorola Moto G). The network is managed by the university, and they are using eduroam. In the university configuration guide they show how to setup a TTLS-PAP connection. The problem is, in my device, the only options available in the phase 2 authentication spinner are None, MSCHAPV2 and GTC. The configuration guide shows screenshots for gingerbread devices where PAP is also available. I've been googling a bit and seems that some ICS devices also have it available. Could this be a problem of this particular device? Or could it be a problem of all JellyBean devices? Is this option available in KitKat? Thanks in advance. ---------- UPDATE
I've checked this option is shown in an old gingerbread phone. Also being shown in a 4.1 tablet.
