In part 1 of this series, I discussed basic password authentication for Active Directory (AD). In this article I will discuss enabling group restrictions and synchronization, and retrieving preferences for AD. I’ll first discuss group restrictions, then synchronization, then retrieving preferences.

Group restrictions and synchronization will require you to somewhat understand the LDAP structure that your AD environment is built upon. Don’t worry, this isn’t as scary as it sounds, and I’ll explain how to find all of the information you’ll require.

For some corporate wikis, it is beneficial to allow anonymous edits; however, anonymous edits in MediaWiki track IP addresses, and in most corporate environments, it is simple to identify a user simply by knowing what IP address they came from. Also, most corporate environments are opposed to allowing non-authenticated write-access to any resource (for good reason).

So, if you wanted to have a wiki, like a wiki for polls, that needed some form of anonymity for users to trust using it, using the LDAP Authentication extension in a clever way can allow you to do this.

The Plotters extension for MediaWiki allows wiki editors to visualize data using scripts created by administrators. Scripts are added in a way similar to the Gadgets extension.

Three types of scripts are available: helpers, preprocessors. and plotters. The script types are loaded in that order so that helpers can be used in preprocessors and plotters, and so that data can be preprocesed before it is plotted.

Wiki editors can use these scripts by using the plot parser function, or tag:

{{#plot:
|renderer=plotkit
|name=<uniquename>
|width=300
|height=300
|script=<scriptname>
|scriptarguments=arg1,arg2,...
|preprocessors=<preprocessorname1>,<preprocessorname2>,...
|preprocessorarguments=<preprocessor1argument1>,<preprocessor1argument2>,...:preprocessor2argument1>,<preprocessor2argument2>,...:...,...
|labels=label1,label2
|datasep=,
|tableclass=wikitable
|data=1,2
2,4}}
