BlackList PAS Plugin: Blacklist users on a Plone site.
BlackList PAS Plugin prevents existing users from logging on a Plone or Zope site.
Sometimes users are very welcome on our sites, sometimes they are not. Whether you need a temporarily freeze of the activity of some members, or a permanent lockout, BlackList Pas Plugin allows you to do so without the loss of information that would be associated with a user deletion.
BlackList Pas Plugin can be used on a Zope or Plone site and it is tested with Plone 2.5 and 3.0 with standard user source and OpenId source.
