crowd

This module provides single sign-on integration between Drupal and an Atlassian Crowd server. It supports detection of the Crowd SSO cookie to provide automatic login of users already authenticated via Crowd. Drupal accounts are created automatically if the user account doesn't already exist. The module also manipulates the standard Drupal user login form validation handlers to authenticate directly against Crowd instead of Drupal. Some additional features are included that allow you to automatically associate Crowd groups with Drupal roles, redirect self-service user forms in Drupal (e.g., reset password) to remote Crowd alternatives, and more.
