/**
 * LoginAction purpose.
 *
 * <p>
 * Processes the login of a user to gain access to the GeoServer Configuration.
 * Currently the defaults are "admin" for username, "geoserver" for password,
 * case insensitive.  This value can be changed in the services.xml file,
 * found in the WEB-INF directory of a running GeoServer.  A page to change
 * the log in would be nice, but it's not here yet.
 * </p>
