SharePoint public-facing website and Microsoft Office documents

Posted: Monday, April 21, 2008 2:40 PM by max

When you have a public-facing site built using SharePoint technologies, opening Microsoft Office documents (Word, Excel, PowerPoint, Visio, etc.) stored on this website requires user to login. You can hit Cancel at the login prompt and still be able to see the document, but having a login prompt displayed to the Internet users, sort of defeats the purpose of having SharePoint-built public facing website with anonymous access turned on. This happens becuase Microsoft Office is closely integrated with MOSS or WSS 3.0 now, and MS Office is now able to recognize that the document is stored within SharePoint, so the appropriate SharePoint authentication/authorization tools kick in. This problem can be resolved mostly by implementing two simple steps (assuming you have already enabled anonymous access on SharePoint):

  1. Disable 'Client Integration' for the web application under Central Admin Home Page >> Application Management >> Authentication Providers
  2. Remove the OPTIONS verb from the <HTTPHandlers> registration line in web.config file

    Thanks Max,  These steps fixed my issues with MS docs under SPS 3.0.

    Thanks for the info.

    One question, which web app's web.config do I need to modify? Central Admin? The one for the SharePoint app?

    Yeah, but that breaks all the integration - which is the point of having it in the first place.

    I am using an ISA Server with FBA and just removing the 'options' and enabling persistent cookies through ISA has solved the problem. Many Thanks

    I have done everything as you specified but when I disable the Client Integration in Central Admin Home Page >> Application Management >> Authentication Providers, it will not show the Documents option under New menu.

    Tejas,

    Documents option is supposed to disappear from the menu as it's a part of client integration. When you disable client integration, you disable documents option ;)

    Max.

    removing OPTIONS verb from the <HTTPHandlers> is disabling Site-Administrations option in the Sharepoint desinger. We can not take site backup.
