MVC - Activating Forms Authentication

I have an MVC 1.0 application with VS2008.

I added config to web.config but app crashes in Default.aspx page code. Not sure why it is loading this page.

I am just using all the defaults for MVC 1.0.

This is my webconfig. Shouldn't my login page be shown in this configuration?

    <!--
        Enabling request validation in view pages would cause validation to occur
        after the input has already been processed by the controller. By default
        MVC performs request validation before a controller processes the input.
        To change this behavior apply the ValidateInputAttribute to a
        controller or action.
