Question

Documentation says it is a standalone component.

Given I have following yaml parsed in the empty index.php file, how to init security and check roles etc.?

# app/config/security.yml
security:
    providers:
        default_provider:
            memory:
                users:
                    ryan:  { password: ryanpass, roles: 'ROLE_USER' }
                    admin: { password: kitten, roles: 'ROLE_ADMIN' }

Matthias Noback hat just writed some documentation about the Security Component. You can read the raw version on github, but it will be merged soon and aviable for you at http://symfony.com/doc/current/components/security/introduction.html

Or you can read his blog posts about the Security Component before changing it to documentation: http://php-and-symfony.matthiasnoback.nl/category/security/
