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.
