+
+Permissions already set by non-grok components are preserved by the
+Grok publisher.
+
+The `@@contents.html` view of folders is protected by
+`zope.ManageContent` and should not be visible to unauthenticated
+users. Instead we are asked to authenticate ourselves::
+
+  >>> print http(r'''
+  ... GET /@@contents.html HTTP/1.1
+  ... ''')
+  HTTP/1.1 401 Unauthorized
+  ...
+  WWW-Authenticate: basic realm="Zope"
+  ...
+
+However, if we make a grant, e.g. on the root object, we can access
+the view just fine:
+
+  >>> from zope.securitypolicy.interfaces import IPrincipalPermissionManager
+  >>> root = getRootFolder()
+  >>> root_perms = IPrincipalPermissionManager(root)
+  >>> root_perms.grantPermissionToPrincipal('zope.ManageContent',
+  ...                                       'zope.anybody')
+  >>> print http(r'''
+  ... GET /@@contents.html HTTP/1.1
+  ... ''')
+  HTTP/1.1 200 Ok
+  ...
+
+But we can still access Grok views not explicitly protected. We create
+an application and add it to the database::
+
+  >>> grok.testing.grok(__name__)
+  >>> from grok.ftests.security.preserve_permissions import App
+  >>> root = getRootFolder()
+  >>> root['app'] = App()
+
+The default view is accessible::
+  
+  >>> from zope.testbrowser.testing import Browser
+  >>> browser = Browser()
+  >>> browser.open('http://localhost/app')
+  >>> print browser.contents
+  Moo!
+
+While the manage view is locked::
+
+  >>> browser.open('http://localhost/app/@@manage')
+  Traceback (most recent call last):
+  ...
+  httperror_seek_wrapper: HTTP Error 401: Unauthorized
+
+When we authenticate, everything works fine::
+
+  >>> browser.addHeader('Authorization', 'Basic mgr:mgrpw')
+  >>> browser.open('http://localhost/app/@@manage')
+  >>> print browser.contents
+  Woo!
