CASAuth(entication) Extension for Mediawiki

A CAS Authentication extension for Mediawiki 1.27, 1.23 (and possibly earlier).

Introduction

The CASAuth extension facilitates CAS authentication for your Mediawiki installation. This particular code is derived from work found here.

This code is customized towards usage for private wikis, with the ability to restrict access to the wiki to specific usernames.

This extension is currently written for and tested against Mediawiki 1.27 and 1.23 with phpCAS 1.3.3. However, if you find it works well against a different version of Mediawiki and/or phpCAS, please feel free to let me know and I will keep track of it in this README.

Security Update

To prevent users from logging in as bureaucrats, via specially crafted user names, be sure to use the latest version of this module, and apply the suggested change to the casNameLookup hook in CASAuthSettings.php, as shown in CASAuthSettings.php.template.

Installation

Assuming a working CAS system, installation should take under 15 minutes. Assume $WIKI is the directory for your wiki.

1. Create folder $WIKI/extensions/CASAuth/

2. Download this source code into that directory

3. Download the phpCAS extension and extract it to the folder $WIKI/extensions/CASAuth/CAS/

4. Add the following line to your LocalSettings.php

   require_once( "$IP/extensions/CASAuth/CASAuth.php" );

5. In the $WIKI/extensions/CASAuth/ directory, copy the CASAuthSettings.php.template file to CASAuthSettings.php and modify it for your environment.

6. You should now have working CAS authentication for your wiki!
