How do I open a report in SSRS 2008 without the user having to provide authentication details?

Question

Summary:
Does anyone know what the minimum we have to do is to get the user to be able to press a button in our app and have the report pop up in an HTML control (Delphi App) with no further input from the user?

Detail:
Authentication is no longer anything to do with IIS in 2008, and a lot of authentication discussion on the web is about IIS and SSRS 2005.

We are looking to display reports within our application and are trying to avoid using the API to re-construct the ReportViewer.

We are hoping to open the reports within an HTML control by passing a URL to the control, along the lines of http://RSServer/ReportServer/ReportDir/ReportName.....

This doesn't work and it looks like it is because the report asks for authentication. We use SQL server authentication for the rest of the app and explicitly want our app installable where domain authentication is patchy at best.

I have enabled Basic authentication which doesn't make much difference, but you don't seem to be able to anable Anonymous Auth, which wouldn't actually be desirable anyway.

Answer 1

I've not tried it, but have you looked at this MSDN blog?

EDIT

This may be of more use - it suggests a method of bypassing authentication without running anonymous access

EDIT 2 With basic authorisation enabled, could you simply provide credentials in the URL? - http://username%3Apassword@servername/etc/etc?
