Known Issues

Since its yet a simple port from Drupal 5's "Drupal" module, it yet have some important issues (present on the old module too):

  • No user data is get from the server (email for example). see
  • Password is sent without cryptography, and is therefore insecure. See
  • The password insertion is done in the site's domain, so they might (but not by this module) capture your password

Use of this module is advised as a compatibility replacement for Drupal 5's distributed authentication, but migration to OpenID is suggested instead.
