phpBB3Auth - Migrate phpBB3 user/password to VB4

For all the phpBB3 administrators who want to migrate their phpBB3 to VB4 and hate the idea that the users have to use the "Forgotten your password?" method to logon to the new VB4 board.

The idea heavily borrowed from the ipbAuth mod created by viarun.

The solution I implemented is that I first hash the password the phpBB3 way and check the hashed password against the entry in phpbb3.users table. When the hashes are the same I use the normal VB4 method to store the password in the VB4 database.

Because I don't like to destroy the original phpBB3.users table I added an extra field "PWD_Synced" to the table and use that field to remember that a password was already synced.

We are running this mod on our brand new VB4 forum and it work perfect. 330+ phpBB3 users already migrated their password to the new board.

Many thanks to viarun and malcolmx in his LDAP Auth Plugin. THANKS guys!

Installation instructions:
  • Add the field "PWD_Synced" in the phpBB3 table phpbb_users. You can use the following statement.
    "ALTER TABLE `phpbb_users` ADD `PWD_Synced` BOOL NOT NULL DEFAULT '0';"
  • copy phpBB3Auth directory to your vb forum installation directory
  • change the path to controller.php directory in phpBB3-plugin.xml
  • copy the hooks_phpBB3.xml to FORUM_ROOT/inclucdes/xml directory
  • in login.php do:
    search for:

Important information

In my documentation I forgot too mention that it is best to install the plug-in after you migrated the data from phpBB3 to VB4. You can leave the phpBB3 database on-line and when you go live the users start to login on VB4 and automagically the password gets migrated to VB4.

Detailed installation instructions and all files needed are in the zip file.

Have fun with it,

I am so jealous right now. I am moving from smf to vb4 at the end of the month and would kill for a mod like this one.

Has anyone had any success getting this to work with vB3? It would really save my bacon if it has already been done by someone else.

Hey gang, I have issues in running this cool phpbbauth system.
After the install, i get this error:

Block Disabled:      (Update License Status)  
Suspended or Unlicensed Members Cannot View Code.

Has anyone else had similar issues and can point me towards whether the fix is to try different paths or to hack the include files?
Thanks guys!

Totally awesome! Just worked perfectly! Wondering if this could be managed at VB5 too, because it's the next step I've to take

Thank you very much

What would be the chances of doing the same with WordPress to VB4?


[edit: working on it myself, almost there]

It only updates on log in, so you do not uninstall it until ALL users have logged in, or until you are willing to put them through the VB lost password procedure

i suggest update it like

we copy phpbb_user table to vb database so we need to have only one table instead of whole phpbb database.

once field "PWD_syn" is filled it notifies to admin with instruction to remove those added lines into login.php and bootstrap.php and removing phpbb3auth directory.
