title: Refused to display "login.microsoftonline.com" in <iframe> in asp.net MVC app
body: <p>I am working on a project where it has two different solutions. &quot;https://example.com&quot; and inside that We have  used to display pages of different project say &quot;https://example123.com&quot;.</p>
  <p>I have implemented Azure AD authentication on &quot;https://example123.com&quot; project. So once it hits that url, AzureAD page shows up for authentication.</p>
  <p>Now I required to work the same authentication thing inside example.com which is using iframe to connect to project example123.com but getting issue -
  login.microsoftonline.com refused to connect.</p>
  <p>Also on console i am getting error as - Refused to display 'https://login.microsoftonline.com/......' in a frame because it set 'X-Frame-Options' to 'deny'.</p>
  <p>Please help on this. Thanks in advance.</p>
