Question
SSRS 2005 SharePoint 2007 integration security woes
I have a SQL 2005 SP2 database running on a server named DBServer.
I have SharePoint 2007 and a single default instance of SSRS 2005 SP2 running together on a server named AppServer.
SSRS is running on its own website on port 5150.
The domain identity named SPWEB runs the SSRS windows service, the SSRS app pool, the SharePoint farm AND it has access to all the databases.
The SSRS Web Site is configured to use NTLM authentication (no kerberos). SharePoint is using "Trusted Account" mode because I wanted to avoid any NTLM "double hop" issues between external users and the database.
Everything is up and running perfectly when you are viewing the site from INSIDE of the domain, logged in as SPWEB. When you are not logged in as SPWEB, and/or you are outside of the domain you get "401 Unauthorized" errors.
On a possibly related note, there have been occasions where the SSRS config tool fails and I need to edit the rsreportserver.config file manually.
I have been working on this all day, but cannot find the right settings to make it work for everyone!

These are very hard problems to troubleshoot, but allow me to explain what I did to get things working.
1. In the central admin, under the applications/Reporting Services Integration, I set the web service URL to http://localhost:5150. I set the authentication mode to "Trusted Account".
2. I created a new DWORD in the AppServer registry called "DisableLoopbackCheck" (HKEY_LOCAL_MACHINE\SYSTEM
3. I made sure my SSRS web site's directory security properties were set to "Integrated Windows Auth" and all other forms of access were disabled.
4. To ensure things work well for external users, I made a shared data source for the report. I deployed the report and the shared data source. I edited the shared data source properties in sharepoint, and configured it to use a hardwired specific windows identity. That effectively handles the double hop issue, without needing to get into kerberos and SPNs. COnfiguring kerberos and SPNs for sharepoint is not simple like a regular web app. Hope this helps someone in the future.
