'import'=>array(
        'application.models.*',
        'application.components.*',
        'application.modules.user.models.*',
        'application.modules.user.components.*',

),
   'modules' => array(

         'user'=>array(

                # enable debuging 
                'debug' => true,

                # encrypting method (php hash function)
                'hash' => 'md5',

                # send activation email
                'sendActivationMail' => true,

                # allow access for non-activated users
                'loginNotActiv' => false,

                # activate user on registration (only sendActivationMail = false)
                'activeAfterRegister' => false,

                # automatically login from registration
                'autoLogin' => true,

                # registration path
                'registrationUrl' => array('/user/registration'),

                # recovery password path
                'recoveryUrl' => array('/user/recovery'),

                'returnUrl' => array('/user/profile'),

                # page after logout
                'returnLogoutUrl' => array('/user/login'),

                # Adding Table refrences 
                'tableUsers' => 'tbl_users',
                'tableProfiles' => 'tbl_profiles',
                'tableProfileFields' => 'tbl_profiles_fields',
                ),
