AuthMoodle

AuthMoodle.php

• an extension of mediawiki's AuthPlugin class so that moodle users can sign in to a mediawiki with the same login/pw
• used in this https://docs.moodle.org mediawiki production site
• download from http://moodle.org/file.php/5/moddata/forum/366/196104/AuthMoodle.php
• first posted by Martin Dougiamas in april 2006 in http://moodle.org/mod/forum/post.php?reply=196104 as an attachment

quoting Martin's instructions based on the root folder of the wikimedia installation:

Save it in extensions/AuthMoodle.php.
Then you just put this in LocalSettings.php:

 require_once( 'extensions/AuthMoodle.php' );
 $wgAuth = new AuthMoodle();
 $wgAuth->setAuthMoodleTablePrefix('');
 $wgAuth->setAuthMoodleDBServer('yoursite.org');
 $wgAuth->setAuthMoodleDBName('yourdb');
 $wgAuth->setAuthMoodleUser('yourdbuser');
 $wgAuth->setAuthMoodlePassword('yourdbpass');
 

Bugs with AuthMoodle in mediawiki 1.7

• preferences are no longer sticky (they pretend to save but don't really save)
  fix: disable this if in includes/SpecialPreferences.php around line 290:

/*
if (!$wgAuth->updateExternalDB($wgUser)) {
    $this->mainPrefsForm( wfMsg( 'externaldberror' ) );
    return;
}
*/ 

• if the moodle database prefix is different from the mediawiki database prefix must match (or be blank)
  fix: edit the function tableName in includes/Database.php around line 1310 and 1313:

function tableName( $name ) {
   global $wgSharedDB, $wgAuth;
   # Skip quoted literals
   if ( $name{0} != '`' ) {
       if ( $this->mTablePrefix !==  &&  strpos( '.', $name ) === false 
            && strpos ($name, $wgAuth->mAuthMoodleTablePrefix) === false ) {

• for mediawiki 1.7, I had to change line 33 to includes/AuthPlugin.php and comment out line 223-226 (refers to a non-existent function)
