// Passport session setup.
//   To support persistent login sessions, Passport needs to be able to
//   serialize users into and deserialize users out of the session.  Typically,
//   this will be as simple as storing the user ID when serializing, and finding
//   the user by ID when deserializing. However, since this example does not
//   have a database of user records, the complete Microsoft graph profile is
//   serialized and deserialized.

// Use the MicrosoftStrategy within Passport.
//   Strategies in Passport require a `verify` function, which accept
//   credentials (in this case, an accessToken, refreshToken, and 37signals
//   profile), and invoke a callback with a user object.

      // represent the logged-in user. In a typical application, you would want
      // to associate the Microsoft account with a user record in your database,
      // and return that user instead.

//   login page.  Otherwise, the primary route function function will be called,
//   which, in this example, will redirect the user to the home page.
