This plugin will protect a closed wiki from accidental ACL misconfiguration. In general, contents of a closed wiki should not be accessible to unauthorized users. Access is configured via ACLs. It is possible to expose some areas of the wiki by granting access to the @ALL group. This plugin blocks application in such cases by internally enforcing two rules:

• Anonymous users (users that have not logged in) are always denied access regardless of the ACL configuration
• The @ALL group can never have any other permissions than 0 - none assigned

Exceptions can be defined in the plugin configuration.

Search and install the plugin using the Extension Manager. Refer to Plugins on how to install plugins manually.

In the norestrictions setting you can optionally define namespaces where the additional access restrictions do not apply. For most wikis, it is recommend to configure such an exception for the wiki namespace to ensure that the wiki's logo can be seen before logging in.
