"Access Control" module configuration not taking affect

[#1]

Anonymous users continue to have access to pages even after access has been disabled via "Access Control" module. Steps tried so far :

1. Uninstall and re-install "Access Control" module

2. In Configuration->workflow->rules->settings->advanced->Rebuild rules caches. Does not help.

Solution here is to "Rebuild permissions" by navigating to Reports -> Status Reports
