OpenID Connect Proxy

The proxy is based on coreos/go-oidc package. It supports simple proxying request based on authentication from any OpenID Connect providers. You can forward either OAuth2 Accesstoken (oauth2) or JWT Token (jwt) in Authorization header. The OAuth2 Accesstokenis the default option for sending to downstream target application. This is useful depending upon your target application configured under proxy section.

In addition to that it has support for two factor authentication which is primarily tested for Dataporten. Two factor can be enabled for selected users/groups or for all the users.

    "engine": {
        "client_id": "<client_id>",
        "client_secret": "<client_secret>",
        "issuer_url": "https://auth.dataporten.no",
        "redirect_url": "http://localhost:8888/oauth2/callback",
        "scopes": "userid",
        "signkey": "testtesttesttest",
        "groups_endpoint": "",
        "token_type": "oauth2",
        "jwt_token_issuer": "https://jwt.example.no",
        "twofactor": {
            "all": false,
            "redirect_on_response": false,
            "principals": "",
            "acr_values": "",
        },
        "logging": {
            "level": "info"
        }
    },
    "server": {
        "port": 8888,
        "health_port": 1337,
        "cert": "cert.pem",
        "key": "key.pem",
        "ssl": false,
        "secure_cookie": false
    }
}

You need to copy the client-id and client-sercret from Dataporten Dashboard. Also make sure you have the redirect_url set accordingly as well as other details.
