Extension:SMF Auth Integration

Overview
This extension integrates MediaWiki with SMF's members table. It has been tested on MediaWiki 1.11.1 through 1.12.0 and is compatible with SMF versions 1.1.x and 2.0.

To get started you only need to configure the relative path to your SMF forum. In the default configuration the wiki login is separate from the forum. You can enable auto authentication by configuring the required settings.

If you decide to use auto authentication, when you click login / logout, the wiki will redirect you to the SMF page and then back to the wiki. For this to work you must be using SMF database sessions (default setting). You also need to ensure local storage of cookies is disabled in SMF.

Another feature is the restriction of editing to one or more SMF member groups. Keep in mind that SMF administrators are always allowed to edit. You can also add one or more member groups to by MediaWiki sysops.

Installation
//                     $wgHooks['AutoAuthenticate'][] = 'AutoAuthenticateSMF'; //original line $wgHooks['UserLoadFromSession'][] = 'AutoAuthenticateSMF'; //fixed line
 * 1) Download the extension and place the it in the wiki/extensions/ folder.
 * 2) Add the code below to the bottom of LocalSettings.php and customize as needed.
 * 3) Since the release of MediaWiki v1.13, this bridge still works for SMF v1.1.x and 2.0.  However, in the Auth_SMF.php, you will need to search for "AutoAuthenticate", and replace it with "UserLoadFromSession" (just one occurrence).  This applies if you wish to use the auto-authentication hook for users with SMF accounts.  AutoAuthenticate has been deprecated since MediaWiki v1.13, and replaced with UserLoadFromSession.
 * 4) To make it work under MW 1.14 you have to change Auth_SMF.php like this

Known Issues

 * The wiki converts underscores in usernames to spaces. For example john_doe becomes John doe. To work around this we check for both cases and use the first registered SMF user. You will need to change the usernames of the later registered user.


 * When wgSMFLogin is disabled if you register a new account from the wiki you will not be redirected back to the wiki. SMF does not have support for this in their code.


 * If the SMF memberName has any square brackets in it, it will cause "MediaWiki internal error. Exception caught inside exception handler". To work around this after line 276 of Auth_SMF.php I added:
