Installing yii-user management module Alias "user.UserModule" is invalid fro new diirctory structure

I m trying to install yii user management module

and i got error

Alias "user.UserModule" is invalid. Make sure it points to an existing PHP file and the file is readable.

I have extracted files under protected/modules folder

also try with extracting files under protected/ folder

but in both case it display issue …

see my config/main.php setting

‘import’=>array(

	'application.models.*',


	'application.components.*',


	#user module starts


	 'application.modules.user.models.*',


     'application.modules.user.components.*',





	#user module ends


),

‘modules’=>array(

	 'user'=>array(


 	   'returnUrl'=>array('/site/index'),


	   'debug' => true,


	  ),





),

‘components’=>array(

		'user'=>array(


	  // enable cookie-based authentication


	  'allowAutoLogin'=>true,


	  'loginUrl'=>array('/user/login'),


	),

‘db’=>array(

		'connectionString' => 'mysql:host=localhost;dbname=dbname',


		'emulatePrepare' => true,


		'username' => 'root',


		'password' => '',


		'charset' => 'utf8',


		'tablePrefix' => '',


	),

I have different directory structure and used file to run applicaiton WebApplicationEndBehavior.php

same as this http://www.yiiframework.com/wiki/63/organize-directories-for-applications-with-front-end-and-back-end-using-webapplicationend-behavior/

I don’t understand where is the problem …

[size="6"]SOLVED[/size]:

when we extract we have folder directory structure like

user

avatar

role

profile

user

registration

we need to place all directory inside user to modules/

so in module will be like

protected/

modules/

  avatar


  role


  profile


  user


  registration
