strongswan site to host example?

Question

There are a million site-to-site and host-to-host examples. I can't seem to find a single site-to-host example. I am looking for the most basic possible example with no certificates at all, that just listens and accepts with a simple username and password from any ipaddress, one that will work with the built-in windows client.

EDIT: When I try the roadwarrior examples it just says my username or password is incorrect in windows

/etc/ipsec.secrets:

: PSK "mypassword"

/etc/ipsec.conf:

conn rw
    leftsubnet=192.168.0.0/16
    leftcert=moonCert.pem
    right=%any
    authby=psk
    auto=add

I get the following error

12[IKE] peer requested EAP, config unacceptable
12[CFG] no alternative config found
12[IKE] peer supports MOBIKE
12[ENC] generating IKE_AUTH response 1 [ N(AUTH_FAILED) ]

when I try to connect in windows and just provide the password with no username.

Any thoughts on how to correct the authentication issue?

Edit 2:

With the following config 
leftsubnet=x.x.0.0/16
left=x.x.x.x
right=%any
leftauth=pubkey
rightauth=eap-mschapv2
eap_identity=%identity
auto=add

and ipsec.secrets

user : EAP "password"

I get the following error

[CFG] selected peer config 'rw'
[IKE] initiating EAP_IDENTITY method (id 0x00)
[IKE] peer supports MOBIKE
[IKE] no private key found for '192.168.254.137'
