title: "error_description":"AADSTS70002: The request body must contain the following parameter: 'client_secret or client_assertion'
body: <p>I used the code in <a href="https://github.com/AzureAD/azure-activedirectory-library-for-java/blob/master/src/samples/public-client-app-sample/src/main/java/PublicClient.java" rel="noreferrer">https://github.com/AzureAD/azure-activedirectory-library-for-java/blob/master/src/samples/public-client-app-sample/src/main/java/PublicClient.java</a>. The only difference is the CLIENT_ID is updated. </p>
  
  <p>I keep getting the error message</p>

  <p>I am not sure how and where to specify this? Is there something that needs to be done in the configuration of the client by the admin?</p>
