Identity Selector technology aims at solving the IdP selection problem. The central proposal in the area is InfoCard, which is realized by Microsoft CardSpace and some open source Identity Selectors. InfoCard can be deployed in direct fashion, but the problem has been availability of SAML 2.0 tokens. This is usually solved by deploying InfoCard in a proxy setup, as shown in Fig-18.
