title: Directory_BindingRedirection error on running a differential query against Azure AD
body: <p>I have an application that performs a query against Azure AD. Running a bog-standard GET for users works perfectly:</p>
  
  <pre><code>https://graph.windows.net/00000000-0000-0000-0000-000000000000/users?api-version=2013-04-05
  </code></pre>
  
  <p>But if I attempt a differential query:</p>
  
  <pre><code>https://graph.windows.net/00000000-0000-0000-0000-000000000000/users?api-version=2013-04-05&amp;deltaLink=
  </code></pre>
  
  <p>I get the following error:</p>
  
  <pre><code>{ 
   "odata.error":
      {
       "code":"Directory_BindingRedirection",
       "message":{"lang":"en","value":"Tenant information is not available locally. Use the following Urls to get the information."},
       "values":[
         {"item":"Url1","value":"https:\/\/directory-s1-ch1.directory.windows.net"},
         {"item":"Url2","value":"https:\/\/directory-s1-sn2.directory.windows.net"},
         {"item":"Url3","value":"https:\/\/directory-s1-bl2.directory.windows.net"},
         {"item":"Url4","value":"https:\/\/directory-s1-co1.directory.windows.net"}]
      }
  }
  </code></pre>
  
  <p><a href="https://stackoverflow.com/questions/31609043/access-azure-ad-graph-api-in-asp-net-mvc-organizational-account">This post</a> suggests that this may be a problem with AzureAD, rather than an expected error case that should be coded for - is this the case, or should this error be handled as per the instructions contained within..?</p>
