This MediaWiki extension allows users in an Elkarte Forum or SMF forum to be automatically signed in if they are of the appropriate usergroup while logged into the forum.

Branches

Branch MediaWiki Elkarte SMF
master 1.38+ 1.0,1.1 2.0,2.1
mw135 1.35 1.0,1.1 2.0,2.1

Configuration

To use, the contents of the ForumSsoProvider directory need to be placed into extensions/ForumSsoProvider. It is then loaded using the 'new' plugin loading method in LocalSettings.php:

wfLoadExtension('ForumSsoProvider');

Required LocalSettings

All settings should be defined prior to calling wfLoadExtension('ForumSsoProvider'); in your LocalSettings.php

Path to Forum Software

$wgFSPPath = '/path/to/smf/root/';

Forum software. Supports smf2.0, smf2.1, elk1.0, elk1.1

$wgFSPSoftware = 'smf2.1';

Optional LocalSettings

Login Groups - Users in this group are signed into MediaWiki. SMF does not have a real group for "Regular" members, it is a pseudo group. Additionally, Local Moderators (Group ID 3) is a special group. Users are only in this group when they are on a board they have been granted moderator permissions on. If you do not specify this, users are granted permission to the wiki by default. If you specify this, users must be in the associated groups to have access to the wiki.

$wgFSPAllowGroups = array(5);

Deny Groups - Prevent users in these groups from being signed into MediaWiki, this is a deny group and takes over the login group.

$wgFSPDenyGroups = array(4);

Admin Groups - Users in these groups are granted sysop access in MediaWiki.

$wgFSPAdminGroups = array(1, 2);

Super Groups - Users in these groups are granted bureaucrat access in MediaWiki.

$wgFSPSuperGroups = array(1);

Interface Groups - Users in these groups are granted interface-admin access in MediaWiki.

$wgFSPInterfaceGroups = array(1);

Special Groups - An key-valued array of {SMF Group ID} => {MediaWiki Group Name}

$wgFSPSpecialGroups = array(
	11 => 'Custom_Wiki_group',
);

Ban checks - Enable checking against bans in SMF. If found it prevents access to MediaWiki.

$wgFSPEnableBanCheck = true;

Lockdown permissions to prevent new account creations/modifications.

$wgGroupPermissions['*']['createaccount']     = false;
$wgGroupPermissions['*']['read']              = true;
$wgGroupPermissions['*']['edit']              = false;
$wgGroupPermissions['*']['createtalk']        = false;
$wgGroupPermissions['*']['createpage']        = false;
$wgGroupPermissions['*']['writeapi']          = false;
$wgGroupPermissions['user']['move']           = true;

Finding your SMF Group ID

  1. Navigate to the Admin Control Panel
  2. Click on Membergroups
  3. Click Modify on the group you are looking for.
  4. In the address bar, you will see group=####, this number is the group id.

Working with Arrays

The configuration file uses basic PHP code.

When you have a single member for the array, you simply just wrap it in the array statement $code = array(1);

If you have 2 members that need to go into the array, use a comma to separate them. $code = array(1,2);

For strings, wrap them in quotes. SMF coding style recommends using single quotes unless necessary. Double quotes signal the PHP parser to use special handling, which might interpret variables and other logic inside the string. This is typically not necessary in the configuration. $code = array('my string');

You may also see the shorthand square brackets to refer to arrays. This is valid as well, but not used in the configuration for simplificy. $code = ['my string'];

Extension Troubleshooting

Set $wgDebugLogFile in your LocalSettings.php:

$wgDebugLogFile = "/some/private/path/MediaWiki.log";

Search for ForumSessionProvider and it will tell you what it is thinking.

This bloats pretty quickly, so you'll want to comment it out after you have resolved your problem.

Wiki Troubleshooting

MediaWiki has built in methods for debugging it. If the extension is acting up and the debugging log is not providing information. Add the following to your LocalSettings.php. This should not be run in a production forum as it may expose sensitive details

$wgShowExceptionDetails = true;
$wgShowSQLErrors = true;
$wgDebugDumpSql  = true;
$wgShowDBErrorBacktrace = true;

Remove when you are done debugging.
