Veja abaixo como fazer um sistema SIMPLES de autenticação utilizando o Zend Framework.

AuthController.php

view->noLayout = true;
$auth = Zend_Auth::getInstance ();
$this->view->auth = $auth->hasIdentity ();
}

function loginAction() {
$this->view->noLayout = true;
$this->view->message = '';
if ($this->_request->isPost ()) {

// collect the data from the user
Zend_Loader::loadClass ( 'Zend_Filter_StripTags' );
$filter = new Zend_Filter_StripTags ( );
$usuario = $filter->filter ( $this->_request->getPost ( 'usuario' ) );
$senha = $filter->filter ( $this->_request->getPost ( 'senha' ) );

if (empty ( $usuario )) {
$this->view->message = 'Favor entrar com um login.';
} else {
// setup Zend_Auth adapter for a database table
Zend_Loader::loadClass ( 'Zend_Auth_Adapter_DbTable' );
$db = Zend_Registry::get ( 'database' );
$authAdapter = new Zend_Auth_Adapter_DbTable ( $db );
$authAdapter->setTableName ( 'users' );
$authAdapter->setIdentityColumn ( 'login' );
$authAdapter->setCredentialColumn ( 'passwd' );

// Set the input credential values to authenticate against
$authAdapter->setIdentity ( $usuario );
$authAdapter->setCredential ( $senha );

// do the authentication
$auth = Zend_Auth::getInstance ();
$result = $auth->authenticate ( $authAdapter );
if ($result->isValid ()) {
// success : store database row to auth's storage system
// (not the password though!)
$data = $authAdapter->getResultRowObject ( null, 'passwd' );
$auth->getStorage ()->write ( $data );
$this->_redirect ( '/' );
} else {
// failure: clear database row from session
$this->view->message = 'Login falhou.';
}
}
}
}

function logoutAction() {
Zend_Auth::getInstance ()->clearIdentity ();
$this->_redirect ( '/' );
}
}

index.phtml

auth): ?>







Logado.
Logout

O grande ponto que temos que nos atentar são essas linhas:

Zend_Loader::loadClass ( 'Zend_Auth_Adapter_DbTable' );
$db = Zend_Registry::get ( 'database' );
$authAdapter = new Zend_Auth_Adapter_DbTable ( $db );
$authAdapter->setTableName ( 'users' );
$authAdapter->setIdentityColumn ( 'login' );
$authAdapter->setCredentialColumn ( 'passwd' );

// Set the input credential values to authenticate against
$authAdapter->setIdentity ( $usuario );
$authAdapter->setCredential ( $senha );

Esse trecho configura o Zend_Auth perguntando qual é a tabela de usuários, coluna de login e a coluna da senha. Tendo esses dados ele faz a autenticação.

Qualquer dúvida, deixe um comment!
