In a multisite, get_site_option() doesn't work in login_redirect filter

[sgissinger]

The following code fails :

function dessange_login_redirect($redirect_to, $request, $user)
{
    return get_site_option(OPT_SITE_URL);
}
add_filter('login_redirect', 'dessange_login_redirect', 1, 3);

unless I connect $wpdb manually before calling get_site_option(), like in the following code

function dessange_login_redirect($redirect_to, $request, $user)
{
    global $wpdb;
    $wpdb->db_connect();

    return get_site_option(OPT_SITE_URL);
}
add_filter('login_redirect', 'dessange_login_redirect', 1, 3);

I'm not able to reproduce an issue in current trunk.

1. Insert a row to wp_sitemeta for testdomain as http://src.wordpress-develop/fake/login/redirect
2. Add this code to mu-plugins/index.php

   define( 'OPT_SITE_URL', 'testdomain' );
   function dessange_login_redirect($redirect_to, $request, $user) {
   	return get_site_option( OPT_SITE_URL );
   }
   add_filter( 'login_redirect', 'dessange_login_redirect', 1, 3 );
   

3. Login with form at http://src.wordpress-develop.dev/wp-login.php
4. Login redirects to http://src.wordpress-develop/fake/login/redirect as expected.

Can you provide more detail on what fails?
