wi fi - How to connect to PEAP MSCHAPv2 Wi-Fi using system certificates in Android 7.1 Nougat?

Android 7.1 has introduced some changes to Wi-Fi connection interface. In 6.0, when selecting PEAP MSCHAPv2 in Wi-Fi connection interface, there were no CA certificates available (unless some had been installed). In 7.1 one can Use system sertificates and Domain input field appears.

So, for example, I want to connect to Eduroam, that requires thawte Primary Root, using login user@uni.org. What am I supposed to type in Domain and Identity fields?
