title: Node JS+passport Authentication+multiple user types
body: <p>I am new to Node.js. </p>
  
  <p>In my application I have two types of user roles. 
  One is trainer and another one is client. </p>
  
  <p>I need to implement social authentication for both users in two different pages. 
  At first i had developed authenticating trainers using passport authentication.
  Developed facebook, google and linked in signups. </p>
  
  <p>Now i want to develop the same to clients also. For this I would like to create seperate callback URLS and seperate apps. </p>
  
  <p>How can I proceed with configuring different callbacks for clients with passport authentication. </p>
  
  <p>Can anyone please help with this issue.</p>
