title: Windows Azure Multi-Factor Authentication Server and SharePoint 2013
body: <p>What I've got is a SharePoint farm on Azure, IaaS and I have installed the new Multi-Factor Authentication Server for Azure.  </p>
  
  <p>It actually works correctly with a normal IIS site, but if you toggle the server to work with a SharePoint web app, subsequent logins to Sharepoint will always generate a 403 error and you won't ever get a call from PhoneFactor.</p>
  
  <p>My question is:  Is there a specific way to configure SharePoint 2013 Authentication to work correctly with the Azure MFA Server?</p>
