I have a sitemap defined in a web.sitemap file and I'm also doing role-based authorization for locations using web.config. I'm using the web.sitemap to generate a menu structure on a Master page, and I wanted to somehow hook the role-based auth from web.config into my menu to hide links to pages that would be denied access from the roles auth.

Is it possible to read the list of <location path=""> and associated role authorizations (allow or deny) from web.config so I can check that against the web.sitemap when generating the menu structure?
