This product provides single sign-on to the CA SSO environments. Users log in to an environment with either product. Once authenticated, they can access both environments. Any authenticated users can access protected resources in either environment without having to reenter credentials, as long as they are authorized. User authorization is based on the policies in effect within each environment.
When allowing users to access secure resources, both products each maintain user credentials in their own session stores. They also have their own proprietary session credentials which are maintained separately. Since these credentials reside in different stores, the Policy Server and CA SSO Policy Server must be part of the same cookie domain. They also must share a user or authentication store.
In a single sign-on configuration, both Policy Servers can be on the same or on different machines. The product can contain a Web Agent, the CA SiteMinder® SPS, or both. You use an Agent or CA SiteMinder® SPS based on your own environment. The CA SSO product uses the eTrust Web Access Control (WAC) agent. You do not need to modify your current environment to enable single sign-on with the product.
