* JSP tag that renders the tag body only if the current user has executed a <b>successful</b> authentication attempt
* <em>during their current session</em>.
*
* <p>This is more restrictive than the {@link UserTag}, which only
* ensures the current user is known to the system, either via a current login or from Remember Me services,
* which only makes the assumption that the current user is who they say they are, and does not guarantee it like
* this tag does.
*
* <p>The logically opposite tag of this one is the {@link NotAuthenticatedTag}
*
* <p>Equivalent to {@link org.apache.shiro.web.tags.AuthenticatedTag}</p>
