until we decided to start ReportBuilder 2.0 (RB2.0). When we started our latest project for SSRS 2008 we already had a similar solution running on SSRS 2005, so we thought that a simple copy-paste of the extensions would give us a headstart.Īnd indeed, after a little bit of tweaking we got both Report Server and Report Manager running. In this blog I will address an issue we came across while using ReportBuilder 2.0 in combination with our security extension. While security extension are a great way to implement tailormade security solutions, extensions can cause quite a few headaches as well. In our environment we were unable to use integrated security on the Report Server, so we decided use Forms Authentication and therefore the need for a custom security extension quickly arose. On my current project we’re making extensive use of a few custom extensions, including a custom security extension. the custom data extension to manipulate a connectionstring or a custom security extension to enable Forms Authentication. SSRS supports a wide variety of extensions that serve different purposes, i.e. One of the ways to add more flexibility to your SQL Server Reporting Services (SSRS) is to extend SSRS with custom extensions.
