/**
* Support for <em>PAM</em>, or <b>P</b>luggable <b>A</b>uthentication <b>M</b>odules, which is
* the capability to authenticate a user against multiple configurable (pluggable) <em>modules</em> (Shiro
* calls these {@link org.apache.shiro.realm.Realm Realm}s).
* <p/>
* The primary class of interest here is the {@link org.apache.shiro.authc.pam.ModularRealmAuthenticator ModularRealmAuthenticator}
* which is an <code>Authenticator</code> implementation that coordinates authentication attempts across
* one or more Realm instances.
* <p/>
* How the <code>ModularRealmAuthenticator</code> actually coordinates this behavior is configurable based on your
* application's needs using an injectible
* {@link AuthenticationStrategy}.
