As an operator, I need authentication with Drupal to act as a service. Currently Fedora must call back into the Drupal database directly using the Islandora DrupalAuthModule. SIdora supports both SI Active Directory (LDAP) and local (external non-SI credentialled) accounts using the Drupal database. A new Authn/Authz framework is needed that support both central and external users without directly calling the Drupal database. It is acceptable to wrap calls to the Drupal database into an HTTP service operating within Drupal.
