Configure Chromebook SSO with Active Directory

First configure Sophos Firewall.

Sophos Chrome Intruder

Sophos Chrome Extension

1. Create an Active Directory server.
   The Chromebook users in the AD must have email addresses that use the domain registered with G Suite. For example, if your registered domain is example.com, AD Chromebook users must have an email address like user@example.com.
2. Change device access to allow Chromebook SSO.
   Go to Administration > Device access and select Chromebook SSO for the zone where the Chromebook users are allowed to connect from, for example, LAN and Wi-Fi.
3. Create or import a valid certificate.
   Note The CN must match the zone/network where the Chromebook users are, for example, gateway.example.com.

   The certificate must not be protected by a passphrase.

   The certificate is used for SSL-encrypted communication with the Chromebooks.
4. Go to Authentication > Services > Chromebook SSO, enable the Chromebook SSO feature and specify the following settings:
   Option

   Description
   Domain	The domain as registered with G Suite, that is, the domain suffix of the email addresses used in G Suite, for example, example.com. This can be different from your Active Directory domain.
   Port	65123
   Certificate	The certificate created/imported above
   Logging level	Select the amount of logging

5. Click Download G Suite app config.
   This will download a JSON file that you need to upload later to G Suite.
6. Open the file with a text editor, enter a value for serverAddress (LAN or DNS IP address of Sophos Firewall), and save.
   Server address must match the certificate’s CN, for example, 10.1.1.1.
7. Create firewall rules.
   1. Create a User/Network rule to allow Google API and Chrome Web Store communication for all devices. This is necessary to push the app to the Chromebooks:
      • Source zones, for example: LAN, Wi-Fi
      • Destination zones, for example: WAN
      • Destination networks: Select the predefined FQDN host groups Google API Hosts and Google Chrome Web Store.
   2. Create a User/Network rule to match known users and to show the captive portal to unknown users to allow internet access to Chromebooks:
      • Source zones, for example: LAN, Wi-Fi
      • Destination zones, for example: WAN
      • Identity: Select the following options: Match known users, Show captive portal to unknown users

      Sort both rules so that rule a) is applied before rule b).

      If you don’t select Show captive portal to unknown users in rule b), we recommend that you create another network rule c) to avoid possible waiting time when contacting the Chrome Web Store.

   3. Create a User/Network rule with the following settings:
      • Rule type: Reject
      • Source zones, for example: LAN, Wi-Fi
      • Destination zones: WAN

      Place the rule at the bottom of the list so that the rule is applied last.
