Advanced Permissions Module for Magento

I need a module like this one: [login to view URL] Advanced Permissions extension for Magento enables admin to assign permissions to users for editing products, managing product categories, managing orders, design and configurations within specific catalogs, Magento store views and websites. This extension will be particularly useful for Magento stores with big catalogs, for multiple store views and for businesses that need to allow users with restricted permissions to manage their own products.
