title: Azure Active Directory, Allowed Token Audiences doesnt appear to do anything
body: <p>I have Azure AD B2C, and am I using it to secure an Azure Function. Users authenticate with the Azure Function by providing a JWT Bearer Token for authorization in the header.</p>
  
  <p>This all works correctly.</p>
  
  <p>I have now tried to apply the Allow Token Audience in the Authentication / Authorization configuration panel.</p>

  <p>I had thought Allow Token Audience would validate the audience (<code>aud</code>) claim of my JWT token - which for my JWT token matches my Client Id.</p>
  
  <p>This does not appear to be the case. All the values I supplied for Allow Token Audience are incorrect, but users are still successfully authenticated.</p>
  
  <p>How is Allow Token Audience supposed to be used?</p>
