public class SingleSignOn extends ValveBase
A Valve that supports a "single sign on" user experience, where the security identity of a user who successfully authenticates to one web application is propagated to other web applications in the same security domain. For successful use, the following requirements must be met:
  • This Valve must be configured on the Container that represents a virtual host (typically an implementation of Host).
  • The Realm that contains the shared user and role information must be configured on the same Container (or a higher one), and not overridden at the web application level.
  • The web applications themselves must use one of the standard Authenticators found in the org.apache.catalina.authenticator package.
