Consider the following scenario. You install Microsoft Office Web Apps on a Microsoft SharePoint Server 2010 server. You search for files in a document library as an anonymous user. In this scenario, the search does not return all the files that match the search conditions.
To resolve this issue, apply the following hotfix updates:
If a user who has View Only permission directly clicks a document that is listed in the search results, the user will receive the following error message:
401 ACCESS DENIED
In this situation, the user must click the View in Browser link that is available under each search result to access the document. Additionally, the user may access segments of other list items in the search results that require additional permissions. These conditions also apply to anonymous users.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
