Open a custom web-application within Dynamics-365 Online using single sign-on

Question

I have been working on something, wherein I have to try and open an existing Office 365 based web-application within Dynamics 365 portal (online). Login into the web-application using the single sign-on provided by Office 365 or the authentication token of the currently logged in user.

To be precise, the operation steps:

Login into Dynamics 365
Click on a button to open the web-application ( within an iFrame or something)
Login into the web-application using the token from the context of the currently logged in user. [ This is where I need help ]

I have tried to open the application using a ribbon button, but the Microsoft login pop-up is blocked by Dynamics 365.

I have been browsing various community pages and blogs, but none of them demonstrate the login procedure or a sample code.

If anyone can provide some sample code or some blog or even a direction which demonstrates the same, it will be of great help!

Token will be generated for particular App say CRM, that may not authenticate you to your custom app as url differs.. — Arun Vinoth
Hello @ArunVinoth, my application already has the capability to use single sign-on, I am able to use the token generated by Office 365 products to login into my application. Was expecting to the do the same in Dynamics 365. — sanktify

According to your question you have 2 problems

Open an external website in an IFrame/Popup
The external website be authenticated with the current CRM user

Problem 1

You could create an HTML WebResource and redirect the page using a FORM tag with action to your website with a JS code in the load event. (you will need to communicate with a HTTPS website, otherwise, the browser security will block the invocation)

<html>
<head>
    <meta http-equiv="X-UA-Compatible" content="IE=edge" charset="utf-8">
    <title>Redirect</title>
    <script src="../../../ClientGlobalContext.js.aspx" type="text/javascript">/script>
    <script>
        $(window).on('load', function () {
           $("#FormId").attr('action', "HTTPS://WebSite.COM");
           $("#FormId").submit();
        });
    </script>

</head>
<body>
    <form id="FormId>
    </form>
 </body>

Problem 2

You will need to register your application in the Azure-AD of the Dynamics CRM instance and configurate the Azure-AD authetication in the corresponding WebSite
