This document summarizes the setup and use of OpenAM, an open source single sign-on (SSO) solution. It describes the initial login process where a user is redirected to OpenAM for authentication before accessing a protected resource. On subsequent access, the user's SSO token is validated before allowing access. It provides instructions for setting up an OpenAM server with a Tomcat container and configuring OpenAM agents on web servers to protect resources based on OpenAM policies. OpenAM supports platforms like Windows, Linux, Tomcat, JBoss and Glassfish. Benchmark results show it can support over 10,000 logins per minute.
