Site Collection Policies - Access Denied

Scenario:
I got the following error while accessing the Site Collection Policies page
"Site Collection Policies - Access Denied"

Solution:
I was using Form Authentication for this web application and so I suspected that as my first culpit and that's what it was. I browsed the same page from my extended Web Application using Windows Authentication and it worked.

So if you are getting the same error , try extending the Web Application on another port with Windows Authentication and you are all set.
