Drupal.my | The nightmare begin.. (technical-need help)

I think we all know about the login/cookie/session problem with firefox 3 on drupal.my

I was called to make the fix and here is the chronology of the event :

Platform : MS Windows XP Pro SP3
Browser : 1. Firefox 3 (3.0.1)
2. IE7

PART A

1. najibx installed drupal V 5 as an addon in his shared hosting account. Some basics and advanced module and themes was installed.
2. the site running well but encounter login problem with firefox 3 user.
3. expected to be server issue, bad modules/files ,etc, I log into the site with admin privileges, disabled all modules. but, problem
   persisted.
4. najibx transfer the site to our hosting server, so I can look further. Dns was allowed to propagate worldwide for 48 hr.
5. a new fresh copy of drupal-510 was downloaded and uploaded to server. no additional modules and themes was installed.
6. drupal was setup with mysqli extension with dpx510 as prefix.
7. PROBLEM PERSISTED : First account (uid 1) setup is giving Access Denied, cannot log into admin area.

8. Suspected to be redirection error or session, a few modification was made to the following files :

   1. .htaccess

   // To redirect all users to access the site WITH the 'www.' prefix,
   // (http://example.com/... will be redirected to http://www.example.com/...)
   // adapt and uncomment the following:
   RewriteCond %{HTTP_HOST} ^drupal.my$ [NC]
   RewriteRule ^(.*)$ http://www.drupal.my/$1 [L,R=301]

   RewriteBase /

   1. settings.php

   $base_url = 'http://www.drupal.my'; // NO trailing slash!
   $cookie_domain = 'www.drupal.my';
   later changed to
   $cookie_domain = '.drupal.my';
   $cookie_domain = 'drupal.my';

9. Firefox browser cache cleared and cookies deleted. Retry on login.

10. PROBLEM PERSISTED

11. Dig into drupal.org to find solutions, few modification to settings.php was made

    ini_set('session.cookie_domain', '.drupal.my');

    A different combination of modification was made to the settings.php.

12. PROBLEM PERSISTED

13. Site was destroyed and db dropped. A new instance of Drupal (v 6.3) was installed using fantastico deluxe, using default
    install.
14. PROBLEM PERSISTED
15. To make sure this is not a server issue, a new php.ini was copied from /etc/php and save to /home/mydrupal.etc chmod 444.
    .htaccess was instructed (PHPRC) to use the new php.ini file which have relaxed setting.
16. PROBLEM PERSISTED
17. A new subdomain was created dev.drupal.my. Default drupal install using fantastico was performed.
18. PROBLEM SOLVED : admin was able to login and confirmed by rajaiskandar
19. To make sure this is not drupal 5 specific issue, a new drupal 5.10 was installed in dev.hostwaves.com.
20. PROBLEM SOLVED : admin was able to login and confirmed by rajaiskandarshah

PART B

1. A Virtual Machine (VM) was deployed inside VmWare Workstation 6 with MS Windows XP Pro SP3, Apache 2.2.8 with mod_ssl,
   PHP 5.2.6 with PECL, MySQL 5.0.51a Essential along with BIND 9.4 and a GPL pop3/smtp mail server was installed in this VM. PHP
   was set to run as apache_module with default php.ini setting with one mysqli extension enabled. NIC was configured to
   self-resolve. Firefox 3 was used as default web browser.
2. Drupal.my was configured as virtual host running as Name-Based virtual server.
3. Drupal 5.10 tar package was extracted and installation script was run using mysqli db extension.
4. PROBLEM PERSISTED ..........
5. Server components was reconfigured to use drupal.org.my, drupal.com.my.

EXPLAINATION

1. To be honest, I have no idea ! I rerun the test with drupal 5.5, and the problem persisted
2. Add yours below...... :

SOLUTIONS ()

1. run drupal.my as www1.drupal.my, en.drupal.my or anything like as long as it is a subdomain. A domain forwarding will be
   configured to redirect www.drupal.my or drupal.my to the destination subdomain.
2. Wait for firefox 3 fix, or Drupal Fix or, Post bug.
