    // The easiest way to create a Shiro SecurityManager with configured
    // realms, users, roles and permissions is to use the simple INI config.
    // We'll do that by using a factory that can ingest a .ini file and
    // return a SecurityManager instance:

    // Use the shiro.ini file at the root of the classpath
    // (file: and url: prefixes load from files and urls respectively):
    Factory<SecurityManager> factory = new IniSecurityManagerFactory("classpath:shiro.ini");
    SecurityManager securityManager = factory.getInstance();

    // for this simple example quickstart, make the SecurityManager
    // accessible as a JVM singleton.  Most applications wouldn't do this
    // and instead rely on their container configuration or web.xml for
    // webapps.  That is outside the scope of this simple quickstart, so
    // we'll just do the bare minimum so you can continue to get a feel
    // for things.
    SecurityUtils.setSecurityManager(securityManager);

    // Now that a simple Shiro environment is set up, let's see what you can do:

    // get the currently executing user:
    Subject currentUser = SecurityUtils.getSubject();

    // Do some stuff with a Session (no need for a web or EJB container!!!)

                    + "Please contact your administrator to unlock it.");

        log.info("May the Schwartz be with you!");
    } else {
