How to get AD user details (azure-mobile-apps-node)

I successfully logged in with AD authentication and redirect to my API page (API page is given below)

I tried "req.azureMobile.user" and "req.user" but both are not returning user details.

I am trying this in desktop browsers

var azureStorage = require('azure-storage');
var azureMobileApps = require('azure-mobile-apps');

var api = {
    get: function (req, res, next) {
        res.status(200).send(req.azureMobile.user);
        // alternative code i tried
        // res.status(200).send(req.user);
    }
};
module.exports = api;
