array('basePath' => APPLICATION_PATH, 'namespace' => '',
'resourceTypes' => array(
'form' => array('path' => 'forms/', 'namespace' => 'Form_'),
'model' => array('path' => 'models/', 'namespace' => 'Model_'),
'plugin' => array('path' => 'plugin/', 'namespace' => 'Plugin_'))));

*/
protected function _initAuth ()

$adp = new Zend_Auth_Adapter_DbTable($db);
$adp->setTableName(USERS_TABLE)
->setIdentityColumn('username')
->setCredentialColumn('password')
->setCredentialTreatment('sha1(?)');
$storage = new Model_Sessions(false, $db);//line 81
$auth = Zend_Auth::getInstance();
$auth->setStorage($storage);
//$this->bootstrap('log');$log=$this->getResource('log');

Your resource autoloader looks good.
I suspect you want Model_Sessions, not Model_sessions (not lower/upper case on "sessions").
Make sure the class Model_Sessions is stored in file application/models/Sessions.php
As a side note, you have your resource autoloader looking for plugins with namespace prefix plugins_. Again, here, I suspect you want uppercase Plugins_.
