Plone: Control User registration

How to ... disable arbitrary new user registration in Plone.


  • login as a manager
  • go to the zope management interface (ZMI) at the root of your site (i.e. )
  • look at the security tab
  • against the Add portal member role ... uncheck the Acquire? check box .. so that permissions aren't inherited from Zope
  • make sure only the Manager checkbox is checked
  • save the form

Disabling new user registration from unauthenticated users this way will also automatically remove the "New user?" and "join" links from the portal interface.
