Privacy is a new plugin for Movable Type that allows you to define "read permissions" for assets in Movable Type (entries, categories and blogs). As a result, readers will first need to authenticate to be able to view the asset. Privacy gives you fine-grained control over who can read your content.
The beauty and power of Privacy, however, lies in its extensible nature - plugins can easily be written that adds a new type of authentication to Privacy which can then be used to mark assets as private. This is most useful for organizations that already have a custom authentication in place. By default, Privacy provides the following types of authentication:
Password - here, readers will be prompted to enter a password to view a private asset
LDAP - available for Movable Type Enterprise users only, this form of authentication allows readers to view private assets using their preexisting LDAP accounts. This is especially useful for Intranet weblogs
Privacy is currently under a public beta, a few bugs may still exist. You are recommended to take a full backup before installing this plugin.
