title: Multiple identity providers with Office 365 based SharePoint 2013 web application
body: <p>I am trying to get multiple identity providers (Google, Facebook, multiple ADFS)  working with a SharePoint 2013 web application provisioned on Office 365.</p>
  
  <p>I know about options related to ADFS and Shibboleth, but am wondering if there is any way to get Azure ACS to handle the authentication for this web app. I do have an on-premise SharePoint 2013 web application working with Azure ACS, but don’t have much info around how to do the same thing with Office 365 or if it’s even possible. </p>
