(Note this is just a poc project and I am aware that it really needs some re ordering and refactoring)

This node.js web app demonstrates:

• SAML2 SSO/SLO authentication provided by Identity Server
• Oauth2 bearer token retrieval provided by Api Manager, using password grant-type
• Call of an API in the Store, obtaining a JWT back

Create a Service Provider according to the following passport strategy:

var samlStrategy = new saml.Strategy({
  path: '/login/callback',    //http://localhost:3000/login/callback set in IS Service Provider
  entryPoint: 'https://localhost:9443/samlsso',
  issuer: 'passport-saml',   //set in IS Service Provider
  protocol: 'http://',
  identifierFormat: 'urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress', //set in IS Service Provider
  logoutUrl: 'https://localhost:9443/samlsso', //default value = entryPoint
  attributeConsumingServiceIndex: xxxxxxxxxx,  //value given to the Service Provider by IS
  privateCert: fs.readFileSync('./private-key.pem', 'utf8'),  //use wso2carbon certificate for signing validation
  cert: fs.readFileSync('./openssl-certwso2.pem', 'utf8')
}

Certificates for signing and signature validation have been extracted using the following:

keytool -importkeystore -srckeystore wso2carbon.jks -destkeystore wso2carbon.p12 -deststoretype PKCS12 -srcalias wso2carbon -deststorepass wso2carbon -destkeypass wso2carbon
openssl pkcs12 -in wso2carbon.p12  -nokeys -out openssl-certwso2.pem
openssl pkcs12 -in wso2carbon.p12  -nodes -nocerts -out private-key.pem

• Publish an API having http://localhost:8080/examples/jsp/jsp2/simpletag/hello.jsp as http endpoint (tomcat samples),
• Subscribe to the published API with an user, generate the client key and secret used for the bearer access token request, and set the node variables cliKey and cliSecret with those values.
• Modify the jsp source {tomcat-home}\webapps\examples\jsp\jsp2\tagfiles\hello.jsp with the provided jsp in this repo, it simply reads the jwt and forwards it setting a response header, so you can get it in this node webapp.

npm install
node app.js

1. http://localhost:3000/login will redirect you to the IS login page: you can login with all LDAP users of the secondary user store,
2. /token will request to the Api Manager a Bearer access token for the currently logged user, using password grant-type,
3. /hellojwt will call the subscribed api using the bearer token, you will get the response of the endpoint with the x-fw5-jwt header containing the jwt.
