title: Understanding resource and authority url
body: <p>I am trying to access azure resource manager through rest and part of the process is to provide an authorization header. I have been able to successfully retrieve the token by using adal library.</p>
  
  <p>I can use either <a href="https://management.core.windows.net/" rel="nofollow">https://management.core.windows.net/</a> or  <a href="https://management.azure.com/" rel="nofollow">https://management.azure.com/</a> as the resource URL to get the token. What is the difference between two ?</p>
  
  <p>I also would like to understand the difference between login.microsoftonline.com/ and <a href="https://login.windows.net/" rel="nofollow">https://login.windows.net/</a> as the authority URL</p>
