Using Wikka PHPBB 3.x
Works with versions: 1.1.6.5 through 1.2
Contributed by Paul Young, using the example code by JeremyCoates .
phpBB3 changed its user authentication mechanism. phpBB3 no longer stores MD5 hashes of passwords; instead it does a "true" one-way, one-time, non-recoverable hash of the password using phpass. The output of the hash is different each time, so you can't just select the password in the phpBB database and do a compare against a MD5 of the submitted password anymore - you have to algorithmically compare them using phpass. They also changed how and where they indicate if a user is active or inactive.
It's not difficult, but you will need to bring in code from phpBB to your Wikka files.
One final note, this code works for me on my server, but could stand to be further tested. Feel free to correct if you find a bug.

Configuration to disable UserRegistration is still required, either patch for 1.1.6.2 or update config setting in 1.1.6.3 (or later) see UserRegistration for more details. See the phpBB 2.x integration page for info about how to edit phpBB to force Wiki-style usernames. On my install this works fine with usernames containing spaces, no caps, etc.
EDIT AlexRust:
I did this today and found two problems:
- There is the ending } missing in function LoadUser.
- After I made these changes I can't logon as admin. Thus I opened a group in phpbb called WIKKA and modified isAdmin as followed:
file: Wakka.class.php
//returns true if user is listed in configuration list as admin
function IsAdmin($user='') {
// $adminstring = $this->config["admin_users"]; // <---
// $adminarray = explode(',' , $adminstring); // <---
// das $adminarray kann für alle User aufgebaut werden, // <---
// die zur phpbb-Gruppe Wikka gehören. // <---
$adminarray = array(); // <---
$query = "SELECT
username,
group_name
FROM
phpbb.phpbb_users u
join phpbb.phpbb_user_group ug on (u.user_id=ug.user_id)

You may change the phpbb database name "phpbb" and the phpbb prefix "phpbb_" into yours.
http://www.wikkawiki.org/URModuleHowTo
Also, if you click the CategoryURModules link at the bottom of that page, you'll find additional code examples in addition to the modules in DarTar's link above.
I had to edit Wakka.class.php as per AlexRust's comments above.
I can login to the wiki with the forum admin's credentials and administrate the wiki - very neat!! I added the original wiki admin to a group called WIKKA in the forum, made the wiki admin an administrator of the forum and he too can continue to administer the wiki - double cool!!
Now to see how I can get our senior school involved :-) I'm just thinking aloud here, but I currently have phpBB as the landing page of a sub directory and so the wiki is not immediately visible. Perhaps the wiki should be the "main" sub directory with a link to the forum, but new users must go to the forum to register - mmmm.
I have saved wiki syntax files of all the pages from a previous Wikka install which I will use to populate this new arrangement - fortunately it is a brand new site only with some additional administrative pages (howtos and such),
A thought: Will this "bridge" still work when the new version of Wikka hits the shelves, I wonder?
