Integration with vBulletin - ipbAuth - Use old Invision Power Board Passwords after migrating to vBulletin

For anyone that's migrating from IPB ( Invision Power Board ) 2.X to vBulletin 4.x. The reason I built this is because the impex import system does not migrate passwords for a move from IPB to vBulletin. This is largely because the passwords are hashed differently, so there's no way to "convert" a password.

This plugin takes a different approach, where you keep the old IPB passwords around, and authenticate users against it first. If they authenticate successfully, then we sync the password the user typed in with vBulletin. Voila...a migration without making your users reset their passwords.

Borrowed heavily from ideas by malcolmx in his LDAP Auth Plugin. THANKS MALCOLMX!

Installation Notes:

1. copy ipbAuth directory to your vb forum installation directory
2. change the path to controller.php directory in ipb-plugin.xml
3. copy the hooks_ipb.xml to FORUM_ROOT/includes/xml directory
4. in login.php search for:

if ($vbulletin->GPC['vb_login_username'] == '')
         {
          eval(standard_error(fetch_error('badlogin', $vbulletin->options['bburl'], ....
         }

And add this hook statement like so:

(if ($vbulletin->GPC['vb_login_username'] == '') 
{ 
  eval(standard_error(fetch_error('badlogin', $vbulletin->options['bburl'], .... 
} 
($hook = vBulletinHook::fetch_hook('ipb_login_hook')) ? eval($hook) : false;

5. activate plugin system (if not done already) in admincp
6. in admin cp import the product at "Plugins & Products -> Download / Upload Plugins", use "Import Plugin Definitions XML File" at the bottom of the page, example import input './ipbAuth/ipb-plugin.xml'
7. in includes/class_bootstrap.php search for:

$show['nopasswordempty']

then change:

defined('DISABLE_PASSWORD_CLEARING') ? 1 : 0;

to:

defined('DISABLE_PASSWORD_CLEARING') ? 0 : 1;

( note that this causes the browser to skip hashing the password in javascript, and passwords will be sent cleartext to the server. technically, a security risk, although many, many, bulletin board systems do this by default. This is the only sensible way to get the cleartext password to be synced though. no other clean way to sync IPB to vB. You can, of course, turn this whole plugin off after most of your users have migrated, and then remove this change. The passwords are properly hashed in the database, and not written to disk, so the risk is relatively low.)


8. Configure the database settings in ipbconfig.inc.php ... this should point to your IPB database that has the members_converge table in it. Be sure to supply a username and password that can read and update the table. Make a copy of the database first...before you turn this plugin on!

9. Make a backup copy of the old IPB database first...before you turn this plugin on!

10. Test

A little story: The whole reason this happened was that IPB treated me like crap. I was a long-time customer of their hosted board service on their 2.X product. Last weekend, I had planned to upgrade to 3.x, and move my board to my own servers. So, I logged into their site and purchased the 3.x product.

It popped up an error that basically said they had flagged the purchase, and were going to keep my money, but not let me download the software until I could be "verified"...perhaps up to 2 days later. So, I decided I didn't like being treated like a thief. I bought a brand-new copy of vB, and wrote this plugin to ease the migration for my board members. I'm posting it here so that hopefully, more people can move away from IPB. Karma rocks.

I'm absolutely sure
I've searched in all internet caves! lol
Your solution is a great solution

I've to migrate my phpBB board this sunday, and the only thing that I can do is overwrite password field with user e-mail, so that user can login to vB forum without recover his password via standard procedure.

My board isn't a tech board and my user are all newbe to forum structure...

[viarun]

I have a beta copy that should work with phpBB. Sent you a pm.

[giorgino]

Thank you viarun

[giorgino]

So viarun. First of all, really thank you for your support and great plugin

I've done this steps:

1. Copied the entire phpbbAuth folder in my root (I'm using vB4 Suite in root of my domain)
2. I haven't changed the path to controller.php. The defaut path seem to be ok for me ( ./phpbbAuth/controller.php )
3. I've copied hooks_phpbb.xml in xml folder (inside /include/xml/ )
4. I've modifyied login.php in vB root
5. I've uploaded hooks_phpbb.xml in Acp
6. I've setup the phpbb information in phpbbconfig.inc.php
test: the login procedure go
7. following your istructions:

in includes/class_bootstrap.php search for:
$show['nopasswordempty']
change: defined('DISABLE_PASSWORD_CLEARING') ? 1 : 0;
to: defined('DISABLE_PASSWORD_CLEARING') ? 0 : 1;

the login procedure go to blank page

[viarun]

Should probably do this via PM, since it's not related to ipb, but rather phpbb.

Sent a PM.

Amazing mod and ive eventually got it working , i had a problem that it wasnt working because my SQL tables were actually different from Viarun , I think this maybe because my IPB install was originally IPB2 but then upgraded to IPB3 so it wasnt a clean install of IPB3

For those of you that have the members table like this : ibf_members , rather than what Viarun has said above with his table being ibf_members_converge .

You will need to use this controller.php file instead of Viaruns :

ATTACHED TO THIS POST

I hope this helps some people as it took me a good 4 hours to finally work it out................yes i know im slow but its been a long day lol.

Enjoy everyone and Massive thank you to viarun for a great mod

Not surprising, as this module wasn't developed for punbb

The module works fine for IPB, and you can see that others ported the module for phpbb.

To make it function for punbb, someone would have to port the code to work in that environment.
