An assertion provides the necessary identity information to facilitate single sign-on at the Resource Partner. The Account Partner generates a SAML 1.1 assertion for a user with an established session. The Account Partner places the assertion in a WS-Federation RequestSecurityTokenResponse message then delivers the token to the Resource Partner. The Resource Partner consumes security tokens and establishes a session that is based on the contents of the WS-Federation security token.
As part of single sign-on configuration, determine how the Account Partner delivers an assertion to a Resource Partner.

A user can visit the Account Partner before going to the Resource Partner. If the user goes to the Account Partner first, a link must generate an HTTP Get request. The hard-coded link points to the Single Sign-on Service of the Account Partner. The request contains the RP Provider ID and optionally other parameters.
The syntax for the link to the Single Sign-on Service is as follows:
https://ap_server:port/affwebservices/public/wsfedsso?wa=wsignin1.0&wtrealm=RP_ID

Resource Partner identity, The entity ID is case-sensitive. Enter it exactly as it appears in the Administrative UI.
When a user starts at the Resource Partner to initiate single sign-on, typically the user selects from a list of Account Partners. The site selection page is in an unprotected realm.
The link on the site selection page points to the Single Sign-on Service at an Account Partner. After the link is selected, the Resource Partner redirects the user to the Account Partner to get the assertion.
