Hi,
I have Reporting services installed with native mode. The reporting services url is exposed to the global network (internet). On my computer I connect from different domain. I can access my reports by providing credentials in the dialog box when I hit the report url. This is ok.
When I try to do the same connecting from Power Pivot I input report server url, provide login, password and I am able to see folders and reports. When I try to open one of them I get the error: Status HTTP 401: Unauthorized. When I click Advanced button it doesn't work (It works before report selection).
Is there a way to bypass this double security check?
