Re: PEAP versions

Hi team

Continuing on my previous question, on the list of supported EAP
methods in wpa_supplicant, the following are mentioned:
EAP-PEAP/MSCHAPv2 (both PEAPv0 and PEAPv1)
EAP-PEAP/TLS (both PEAPv0 and PEAPv1)
EAP-PEAP/GTC (both PEAPv0 and PEAPv1)
EAP-PEAP/OTP (both PEAPv0 and PEAPv1)
EAP-PEAP/MD5-Challenge (both PEAPv0 and PEAPv1)

But I thought PEAPv0 is from Microsoft and meant for MSCHAPv2 while
PEAPv1 is from Cisco and was defined for support for GTC. And how does
PEAPv2 fit into the picture? Does it provide more security by binding
the inner authentication to the outer server TLS authentication?
