AuthMoodle.php

quoting Martin:

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');
