[strongSwan] Windows connection and PSK

I'm trying to setup Strongswan for both iOS devices and Windows machines. I 
would like to use PSK and/or passwords and not have the user install any 
certificate on his side.

I've setup 2 types of connections: one using IKEv2 and one using IKEv1+XAuth. 
Both work well with iOS devices and PSK setup.

The problem starts when I try to connect from a Windows machine. I was not 
able yet to setup Strongswan to accept connections from Windows without using 
a certificate. When using IKEv2 - Windows does not even offer an option to 
enter PSK.
