[strongSwan] EAP-PEAP

[korsar182 at gmail.com]

Hi,
I try to connect strongswan client on Ubuntu 18.04 to the strongswan  
server using EAP-PEAP on Windows Network Policy Server, but it doesn't  
work. Windows clients connect fine.

Server logs:
charon: 11[CFG] RADIUS Access-Request timed out after 4 attempts
charon: 11[IKE] EAP method EAP_PEAP failed for peer MyVPNuser

Client logs:
