title: Azure AD Authentication with SharePoint 2013 Not Working
body: <p>I am attempting to establish authentication using Azure AD within a SharePoint 2013 site.</p>
  
  <p>I followed the instructions in the article <a href="http://technet.microsoft.com/en-us/library/dn635311(v=office.15).aspx" rel="nofollow">here</a>.</p>
  
  <p>It looks like everything has been setup correctly.  When I navigate to the SharePoint site, I am presented with a drop down to select the authentication provider.  If I choose the AAD provider, I can enter my credentials.  However, at this point, I am returned to the sign in page.  From here the process repeats.</p>
  
  <p>The really strange thing is I have seen it actually work a time or two.</p>
  
  <p>Since I am not <em>technically</em> getting any errors, I am not sure how to troubleshoot this one.</p>
  
  <p>Any suggestions or ideas as to what to look at?</p>
