## org.apache.catalina.authenticator
Class SingleSignOnEntry

    java.lang.Object
      org.apache.catalina.authenticator.SingleSignOnEntry

    public class SingleSignOnEntry

extends java.lang.Object

A class that represents entries in the cache of authenticated users. This is necessary to make it available to `AuthenticatorBase` subclasses that need it in order to perform reauthentications when SingleSignOn is in use.
