3.1. Introduction

Zend_Auth provides an API for authentication and includes concrete authentication adapters for common use case scenarios.

Zend_Auth is concerned only with authentication and not with authorization. Authentication is loosely defined as determining whether an entity actually is what it purports to be (i.e., identification), based on some set of credentials. Authorization, the process of deciding whether to allow an entity access to, or to perform operations upon, other entities is outside the scope of Zend_Auth. For more information about authorization and access control with the Zend Framework, please see Zend_Acl. Замечание

The Zend_Auth class implements the Singleton pattern - only one instance of the class is available - through its static getInstance() method. This means that using the new operator and the clone keyword will not work with the Zend_Auth class; use Zend_Auth::getInstance() instead.

3.1.1. Adapters

A Zend_Auth adapter is used to authenticate against a particular type of authentication service, such as LDAP, RDBMS, or file-based storage. Different adapters are likely to have vastly different options and behaviors, but some basic things are common among authentication adapters. For example, accepting authentication credentials (including a purported identity), performing queries against the authentication service, and returning results are common to Zend_Auth adapters.
