When domain users search SharePoint 2010, they are unable to open the document from the search results. They are prompted for the Window Login credentials, but their credentials do not allow them to open the file from the search. They are able to browse to the file and open it without any prompts or problems. They are also able to save a file to their computer from the search and then open it that way.
When they have their search results and the prompt for the Windows Login, if I login with my administrative credentials, I am prompted to Check Out & Open, Open, or Cancel. Opening works for me.
It appears, to me, that this would point to a permissions issue. How do I go about granting the domain users the same permissions in search, as they would if they browsed directly to the document? The users state that they did not have this issue when they were on Windows XP. Only since they have been upgraded to Windows 7, has this started. I have had them try this on PDFs and Word Documents.
