Integrates Drupal with the RESTAuth system.
RESTAuth is a shared user authentication system to avoid many different accounts and passwords for various systems in an organization. A central authentication server stores the user credentials and client systems (like Drupal) can authenticate users via a lightweight RESTful web service interface.
Take a look at the README.txt for installation instructions.
RESTAuth was developed at Fachschaft Informatik (the computer science students union) and is currently in use for sharing accounts between several Drupal sites, MediaWiki installations, Etherpad and Apache basic authentication.
