Description

This module provides API used for and during the authentication.
In particular this module provides APIs: 

  • to triggers additional security checks when a user failed to authenticate multiple times in a given time window
  • to allows users reset their password when they forgot it
  • to manage the dedicated /authenticate/ URL resource type.

Configuration

 

The configuration of the module allows to setup three information:

  • the authentication failure strategies (default is CAPTCHA)
  • the maximum number of failing login attempts authorized before activating a strategy (default is 3)
  • the time window during which those attempts should occur (default is 5 minutes)

Setting no strategy or 0 to the maximum number of attempts, or to the time window will disable the feature.
This configuration is available in the Administration > Authentication page by default.

Starting with XWiki 11.10 it is now possible to enable or disable the authentication security mechanism. Note that disabling it will also clear out all information related to the login failures: this might unlock some users in case of problems.

Authentication Security Checks

Authentication Failure Manager

This component is responsible to record the authentication failures, and to trigger the strategies based on the given configuration.

Authentication Failure Strategies

Two strategies are currently implemented and available.

CAPTCHA

This is the default strategy. When a user reached the limit number of authentication attempts, a CAPTCHA is displayed in the login page, and the user have to solve it in order to be login.

Disable Account

 

This strategy will automatically disable the user account in case of repeated authentication failure. In that case he needs to contact an administrator of the wiki to enable it back.

Authenticate URL resource type

 

This module provides the component to handle the /authenticate/ URLs.
This URL allows to handle two actions with the following schemes:

  • /authenticate/reset allows a user to reset her password
  • /authenticate/forgot allows a user to retrieve her username

Reset password

A dedicated component is provided to allow a user who forgot her password to retrieve it. The process is using an intermediate code that needs to be sent to the user by a protected mean such as an email sent to her.

Events

List of provided events:

  • AuthenticationFailureEvent which is triggered whenever a user fails his authentication
  • AuthenticationFailureLimitReachedEvent which is triggered when the authentication failure manager detected that a user reached the limit of authentication failures.
  • 13.3+ Form and Basic authenticators trigger the new event UserAuthenticatedEvent whenever a user authenticates.
