I recently extended my SharePoint 2013 web application and added ADFS as an authentication method on the new zone.
The Microsoft Office Word integration works fine and a user is able to open a document directly from a document library and edit and save it. When the user's ADFS token has expired and he clicks save he gets an error in Word stating "Upload Failed" and a button "Log in".
Is it expected behavior that Word doesn't trigger a re-authentication against the ADFS server to get a new token? We have Single Sign On and a browser refresh gets a new token instantly.
The "Log in" button in the error message doesn't do anything when clicked. Am I missing some setup?
