Extension:Access Control List

With the Access Control List extension (ACLe) you can restrict the access to different elements of your wiki for single users or entire user groups. It allows to easily configure and manage custom rights via a comprehensive GUI. Main features of the Access Control List extension are:
 * Access management to system features via graphical user interface.
 * Protection of namespaces (e.g. for pages in the 'template' namespace), categories (e.g. for articles in the category 'confidential') and single wiki pages.
 * Definition of user groups, "groups of groups" and group hierarchies.
 * Import and re-use of users and groups via LDAP (Lightweight Directory Access Protocol).
 * Combination of own permission sets out of system features.
 * Assignment of permission sets to groups or individual users.
 * Protection of semantic properties (e.g. to restrict access to the property 'salary').

The specific features of the ACLe are also listed at the page Category:Page specific user rights extensions. First versions of this extension have been developed within Project Halo and was part of the discontinued SMW+. The latest version was developed by W. Breiter (KIT).
