Intranet/Intranet Client Configuration

MediaWiki is accessed via a web browser and clients may need some configuration changes to work properly with the Intranet as documented here. Assuming that the wiki is using a TLS certificate that is signed by the corporate CA then the client system must also trust that CA. IE, Chrome and Chromium will use the Windows trust store which should include the Enterprise CA. Firefox on Windows does not yet but has support for it which is disabled by default. All clients must be "domain joined". You can check that you have valid Kerberos tickets on both Windows and Linux with the klist command.

enable_local_policy.js: local_policy.cfg: Copy the two files to a central location that is accessible to all client PCs. One possibility is \\example.co.uk\SYSVOL\example.co.uk\firefox, that is use the SYSVOL share on your domain controllers. These files are tiny so there should be no problems.

Create a Group Policy object or edit an existing one and create two File items:

Linux
Create a directory to hold settings. The first one is for Chrome and the second one is for Chromium. Create a file such as /etc/opt/chrome/policies/managed/local_policy.json:
