We have a silverlight application thats behind a ISA server, and the users have to authenticate against the ISA server.
In the silverlight application we uses Sharepoint 2007 as a documentlibrary (the backend uploads the documents).
When the user wants to open a document, we use a javascript, editDocumentWithProgID2, and HtmlPage.Window.Invoke(...) in silverlight.
The problem is that word/excel shows a new login dialog, so the users have to login again. Is there a way of avoiding this login dialog?
