3.1 Multi Domain 302 redirecting to network admin site

I've recently installed 3.1 wordpress, enabled multi-site as sub-directory install, installed domain-mapping plugin, entered my IP address of server and setup my first satellite site.

1) Why would this secondary site (and any additional sites) be 302 redirecting to the main site instead of just displaying a new site. The new set of tables was created fine as well.

2) What should I enter in the new site for the subdirectory if nothing even uses those directories?

The documentation still seems to reflect 3.0 stuff and I'm using everything from scratch as supplied today.

Best Regards

My wp_config.php is setup with this:

define('WP_DEBUG', false);
define('WP_ALLOW_MULTISITE', true);
define( 'MULTISITE', true );
define( 'SUBDOMAIN_INSTALL', false );
$base = '/';
define( 'DOMAIN_CURRENT_SITE', 'www.mymaindomain.com' );
define( 'PATH_CURRENT_SITE', '/' );
define( 'SITE_ID_CURRENT_SITE', 1 );
define( 'BLOG_ID_CURRENT_SITE', 1 );
define('SUNRISE','on');
