This project is not covered by Drupal’s security advisory policy.


CoSign is an open-source project originally designed to provide the University of Michigan with a secure single sign-on web authentication system.

CoSign authenticates users on the web server and then provides an environment variable for the users' name. When the users access a part of the site that requires authentication, the presence of that variable allows access without having to sign-on again.

The Drupal 6 version of this module depends on the webserver auth module.
