ja:auth:punbb

PunBB 認証バックエンド

このバックエンドプログラムは同じサーバー内にインストールされている掲示板システム、PunBB 1.2.x または 1.3.x で認証を行うものです。これにより、PunBBのアカウントでDokuWikiにもログインできるようになります。(PunBBのクッキーを利用し、シングルサインオンをできるようにします。)

動作条件

  • 最近のバージョン、PunBB 1.2.x (1.3.xはベータ版でサポート)がインストールされていること。
  • PunBBとDokuWikiは同じドメイン上であること。
  • magic_quotes_gpc が off であること。1)

設定

このバックエンドはPunBBの設定を利用するので、PunBBがインストールされているディレクトリの位置をPUN_ROOTをdefine文で設定します。DokuWikiディレクトリのconf/local.protected.phpに次のように設定を追加します。

  $conf['useacl']  =1;
  $conf['authtype']='punbb';
  define('PUN_ROOT','/path/to/punbb/');

このパスは絶対パスでなければいけません。また、末尾にスラッシュ(/)が必要です。たとえば、/var/www/free.fr/2/8/mysite/punbb/のようになります。

管理者ユーザーとして認識させるには、PunBBの管理者グループの名前をDokuWiki設定のsuperuserオプションで設定する必要があります。PunBBの管理者グループの名前の付け方は言語パックによって異なります。英語の場合は@Administratorsですが、フランス語では@Administrateursとなっています。

ソースコードとインストール

PunBB 1.2.x

DokuWiki 2008-05-05までのバージョンでは、このバックエンドはDokuWikiのソースに含まれていました。それ以降のバージョンではこのバックエンドが含まれていません。

インストールするには、DokuWikiディレクトリにinc/auth/punbb.class.phpファイルを新規に作成して、つぎのコードをコピー&ペーストします。

  • Some username are not understand by DokuWiki (Pérot became P�rot or Pérot)

DokuWiki uses UTF-8 and PunBB ISO8859-1, so this is just a character encoding problem. In order to get the right usernames, open /dokuwiki/inc/auth/punbb.class.php, find (l136 on v. 2007-06-26b) :

    if(isset($pun_user) && !$pun_user['is_guest']){
      // okay we're logged in - set the globals
      $USERINFO['pass'] = $pun_user['password'];
      $USERINFO['name'] = $pun_user['realname'];
      $USERINFO['mail'] = $pun_user['email'];
      $USERINFO['grps'] = array($pun_user['g_title']);
 
      $_SERVER['REMOTE_USER'] = $pun_user['username'];
      $_SESSION[DOKU_COOKIE]['auth']['user'] = $pun_user['username'];
      $_SESSION[DOKU_COOKIE]['auth']['info'] = $USERINFO;
      return true;
    }

And replace by :

    if(isset($pun_user) && !$pun_user['is_guest']){
      // okay we're logged in - set the globals
      $USERINFO['pass'] = $pun_user['password'];
      $USERINFO['name'] = utf8_encode($pun_user['realname']);
      $USERINFO['mail'] = $pun_user['email'];
      $USERINFO['grps'] = array($pun_user['g_title']);
 
      $_SERVER['REMOTE_USER'] = utf8_encode($pun_user['username']);
      $_SESSION[DOKU_COOKIE]['auth']['user'] = utf8_encode($pun_user['username']);
      $_SESSION[DOKU_COOKIE]['auth']['info'] = $USERINFO;
      return true;
    }

  • As punbb 1.3 will support utf8, a better patch is :
          // okay we're logged in - set the globals
          $USERINFO['pass'] = $pun_user['password'];
          $USERINFO['name'] = preg_match('/^1\.2/',$pun_config['o_cur_version']) ? utf8_encode($pun_user['realname']) : $pun_user['realname'];
          $USERINFO['mail'] = $pun_user['email'];
          $USERINFO['grps'] = array($pun_user['g_title']);

    (only the $USERINFO['name'] line is changed)

  • I think there is a problem when you use DokuWiki's ACL : a regular member with appropriate rights under PunBB can not edit a page though ACL seems properly configured (changes forbidden in : but allowed in :help: ). The problem may come from the fact DokuWiki has a “user” group while PunBB has a “members” and this is not *always* correctly seen.
    • yann: edit the file conf/acl.auth.php, add there the group members (duplicate the line with “user”, and replace “user” by “members”.
    • Better yet, use the group Members as is defined in the table groups in the PunBB MySQL database.

utf8関数でエラーが出る問題

※PunBB-1.3.4/DokuWiki-2009-12-25の場合

PunBBのinclude/utf8ディレクトリ内には、utf8用の文字列操作関数を定義したファイルが複数存在する。これらは実際のところDokuWikiのinc/utf8.phpのコードをバラにして格納したものである。このままだと統合したときに「同じ関数が再定義されている」というエラーが出てしまう。そこで、PunBBでもDokuWiki内のinc/utf8.phpのコードを使うように変更する。

PunBB内の、include/essentials.php内の25行目~27行目をコメントアウトし、DOKU_ROOTにDokuWikiの絶対パスを定義して、inc/utf8.phpを読み込ませる。

変更前

// Load UTF-8 functions
require FORUM_ROOT.'include/utf8/utf8.php';
require FORUM_ROOT.'include/utf8/ucwords.php';
require FORUM_ROOT.'include/utf8/trim.php';

変更後

// Load UTF-8 functions
//require FORUM_ROOT.'include/utf8/utf8.php';
//require FORUM_ROOT.'include/utf8/ucwords.php';
//require FORUM_ROOT.'include/utf8/trim.php';
if(!defined('DOKU_ROOT')){
  define('DOKU_ROOT','/home/wiki/');
}
require DOKU_ROOT.'inc/utf8.php';
