Aparentemente, a política "Configurar a lista de extensões instaladas pela força" da ADM simplesmente não funciona.
Então, acabei tendo que usar o método de registro.
NOTA: Se estiver usando o método de registro, a extensão será desativada automaticamente na versão 25 do Chrome. Observe também que, para o Chrome 25 e superior, a política de ADM agora funciona.
- Find the extension ID of your desired extension. This is the unique ID of the extension in the Chrome webstore. You can see this ID in the URL of the extension ie:
https://chrome.google.com/webstore/detail/gighmmpiobklfepjocnamgkkbiglidom
or, Open the extensions list in Chrome; tick the Developer Mode tick box and then click the arrow next to the extension you want to deploy - the extension ID will be underneath the extension's heading.
At this point, it is worth making note of the extension's version number too, as you will need this later on in the deployment.
- Open a browser other than chrome - Firefox will work fine. Paste the following line into the address bar, replacing the ----- with the extension ID
https://clients2.google.com/service/update2/crx?response=redirect&x=id%3D-----%26uc Press enter to access this URL; you will be prompted to save the .crx file.
Copy this .crx file to your deployment shared folder eg \Server\SoftwareDeployment\ChromeExtensions\.crx

Em seguida, adicione as chaves de registro em computer configuration\preferences\windows settings\registry
:
Create the following registry key values:
HKEY_LOCAL_MACHINE\SOFTWARE\Google\Chrome\Extensions\[id of your extension crx]\path TYPE: REG_SZ VALUE: "\server\NETLOGON\path\to\your\extension.crx" HKEY_LOCAL_MACHINE\SOFTWARE\Google\Chrome\Extensions\[id of your extension crx]\version TYPE: REG_SZ VALUE: [version of your .crx as specified in the manifest]
