Multisite login and redirect to users main blog,

I solved this and I only use:

wp_login_form();

Since I don’t want users to get access to the wp-admin area at all I use the following code:

// Restrict users from accessing the admin-area
function restrict_admin()
{
    if ( ! current_user_can( 'manage_sites' ) ) {
        wp_redirect( site_url() );
    }
}
add_action( 'admin_init', 'restrict_admin', 1 );

// Disable admin-bar for users
add_action('after_setup_theme', 'remove_admin_bar');

function remove_admin_bar() {
    if (!current_user_can('manage_sites') && !is_admin()) {
        show_admin_bar(false);
    }
}

Kind regards
Johan
