Disallow access to a Plone site and its children if user is anonymous

Project description

What is iw.rejectanonymous ?

This package is made to reject unconditionnally anonymous users from a Plone site, without any change in your security policy matrix or workflows. They should get redirected by plone to login form. The basic use case is an extranet, where all visitors must be authenticated.

Works with

Plone 3, 4, 5


Add iw.rejectanonymous to the eggs option of your plone.recipe.zope2instance part

recipe = plone.recipe.zope2instance
eggs =
# The ZCML slug is no more required with Plone 3.3 and up
zcml =

Re-run buildout, then open the “Security” control panel of any Plone site of your instance. A new Private site checkbox lets you (de)activate iw.rejectanonymous.


iw.rejectanonymous enables the publication of some resources to the anonymous user, more specifically to enable all media and resources required from the standard loging page and the password reset page.

Adding valid ids

If your customized logging page requires some specific images or your site policy component provides a signup page which name is not login_form you may add additional ids (url last part) that are available to anonymous users.

from iw.rejectanonymous import addValidIds
addValidIds('some_image.png', 'my_login_form')

Adding valid subparts

If you want to let anonymous users browse the pages of some folders, you need to add valid subparts.

from iw.rejectanonymous import addValidSubparts
addValidSubparts('disclaimer', 'public_section')

Adding valid subparts prefixes

If you want to let anonymous users browse the pages of some folders with specific prefixes, you need to add valid subpart prefixes.

from iw.rejectanonymous import addValidSubpartPrefixes

Hiding viewlets

You may hide viewlets from the views of the site (login form, password reset form). You need for this to add such lines in your site policy ZCML.


Keep the original viewlet name.


iw.rejectanonymous.IPrivateSite the marker interface set to private sites


Keep the original manager


Keep the original viewlet class


Choose a permission that is not granted to an anonymous user but to anyone else. cmf.SetOwnProperties is a good choice if your site has the standard security policy.

See how we hide the plone.personal_bar and the plone.searchbox in the configure.zcml of this component.
