Exploring best approach to integrate portal built on LiveSite with CA SiteMinder to externalize authentication and coarse grained authorization to SiteMinder. Standard approach would be to protect the LiveSite portal with a SiteMinder Web Agent installed in the web server tier and configure LiveSite to defer authentication and authorization to SiteMinder via the SM_USER HTTP Header. Would appreciate any feedback from the community on the technical feasibility of this approach (out-of-the-box with LiveSite) or alternate integration approaches.
