Description

The Shibboleth authentication module provides user authentication with Shibboleth single sign-on systems (both v1.3 and v2.0) as well as some authorization features (automatic role assignment based on Shibboleth attributes).

The module doesn't sufficiently confirm the user's active status in Drupal when authenticating a user whose account could be blocked.
