includePaths.library = APPLICATION_PATH "/../library"

bootstrap.class = "Bootstrap"

admin.bootstrap.path = APPLICATION_PATH "/modules/admin/Bootstrap.php"
admin.bootstrap.class = "admin_Bootstrap"

# Front Controller
resources.frontController.controllerDirectory = APPLICATION_PATH "/controllers"
resources.frontController.env = APPLICATION_ENV

# Session
resources.session.name = "ZendSession"
resources.session.save_path = APPLICATION_PATH "/../data/session"
resources.session.remember_me_seconds = 86400

# Layout
resources.layout.layout = "layout"
resources.layout.layoutPath = APPLICATION_PATH "/layouts"
admin.resources.layout.layout = "admin"
admin.resources.layout.layoutPath = APPLICATION_PATH "/modules/admin/layouts"

resources.view.basePath = APPLICATION_PATH "/views/"
resources.view[] =

resources.frontController.moduleDirectory = APPLICATION_PATH "/modules"
resources.modules[] =
resources.view[] =
admin.resources.view[] =

I use plugin approach with this code I have written:

in main Bootstrap:

protected function _initPlugins()
{
        // Access plugin
        $front = Zend_Controller_Front::getInstance(); 
        $front->registerPlugin(new MyApp_Plugin_Module());
}

In plugin directory:

class MyApp_Plugin_Module extends Zend_Controller_Plugin_Abstract
{

    public function preDispatch(Zend_Controller_Request_Abstract $request)
    {

        $module = $request->getModuleName();
        $layout = Zend_Layout::getMvcInstance();

        // check module and automatically set layout
        $layoutsDir = $layout->getLayoutPath();
        // check if module layout exists else use default
        if(file_exists($layoutsDir . DIRECTORY_SEPARATOR . $module . ".phtml")) {
            $layout->setLayout($module);
        } else {
            $layout->setLayout("default");
        }
}

Hope it helps.
