### 2.2.5. Hints For the Core Authentication Module

The Core module is a meta-module.

The Core module lets you set up the list of modules available, and specify what types of client applications can authenticate with which modules. It also lets you configure connection pools for access to directory servers, and whether to retain objects used during authentication for use during logout. Furthermore, the Core module lets you set defaults used when configuring authentication in a particular realm.

The Core Authentication module is divided into seven sections:

- Section 2.2.5.1, “Core - Global Attributes”

- Section 2.2.5.2, “Core - Realm Attributes”

- Section 2.2.5.3, “Core - Persistent Cookie (Legacy)”

- Section 2.2.5.4, “Core - Account Lockout”

- Section 2.2.5.5, “Core - General”

- Section 2.2.5.6, “Core - Security”

- Section 2.2.5.7, “Core - Post Authentication Processing”
