Proxy Mode with the SiteMinder Connector at the Relying Party
If Federation Manager is communicating with SiteMinder in proxy mode, all requests still pass through Federation Manager; however, Federation Manager has to establish a SiteMinder session with the Policy Server so that when the user requests SiteMinder-protected resources he is not rechallenged. The request is redirected to the target web server, which is protected by a SiteMinder Web Agent.
The following figure shows a proxy mode architecture with the SiteMinder Connector. This figure is from the perspective of the relying party.

The previous figure shows the following communication flow at the relying party:
- A user requests a federated resource and is redirected to the relying party's assertion consumer service.
- Based on the data received in the assertion, Federation Manager authenticates the user, which includes communicating with the user directory to complete the user disambiguation process.
- The SiteMinder Connector, as part of Federation Manager, contacts the custom authentication scheme at the SiteMinder Policy Server. A SiteMinder session ticket is created by the Policy Server, which it sends to Federation Manager. Federation Manager then creates a session cookie that includes the ticket. Establishing a SiteMinder session ensures the user is not challenged later when accessing the target resource.
- Federation Manager returns a redirect response back to the user's browser.
- The browser redirects the user to Federation Manager and Federation Manager proxies the request to the web server with the target resource, which is protected by the SiteMinder Web Agent.
- The SiteMinder Web Agent and Policy Server perform the authorization process.
After successful authorization, the target resource is presented to the user's browser.
