DokuWiki Shibboleth authentication backend updated and moved to GitHub

Few years ago I wrote a Shibboleth authentication backend for DokuWiki. So far it worked well, but recently I needed some additional features, so I made few modifications and enhancements:

• moved the project to GitHub
• changed the license from the restrictive GPL2 to FreeBSD
• added an option to use the DokuWiki session instead of the Shibboleth session - the Shibboleth session is checked only upon login
• the authentication backend and the login plugin are now in one single package
• improved example configuration - better formatting and comments, you can edit it, put it in the conf/ directory and simply include it in your local.php file
• refactored the code to be more PHP 5.x compliant

You can get the code from the GitHub repository.
