2.7. Enable and test authentication offload

1. Start a Web Shell to Ubuntu18.04 Services (Systems > Ubuntu18.04 Services > ACCESS > Web Shell). MAKE SURE you are accessing Ubuntu18.04 Services and not the Ubuntu18.04 Client.

2. Enter the following commands in the Web Shell - NOTE You will need to type these commands into the Web Shell as it lacks copy-and-paste capabilities:

clear
tail -f -n 0 /var/log/squid/access.log

3. Visit a few secure (HTTPS) websites (non-banking) using Chrome on the Windows Client and confirm that access is still being logged. You should see log entries of the sites and URLs visited but the username field (immediately after the URI) will be blank ("-"), similar to the example below:

SSL Orchestrator does not pass authenticated usernames to a proxy service unless explicitly configured to do so. In the next step you will enable this feature.

4. On SSL Orchestrator select SSL Orchestrator > Configuration from the Main menu on the left

5. Click Services on the horizontal menu and then click on ssloS_SquidProxy. The Summary page will load for the Squid proxy service.

6. Click the edit icon () to the right of Service

7. Scroll down the Service Properties screen and select the Authentication Offload checkbox. Doing so will cause SSL Orchestrator to inject an "X-Authenticated-User" header into the HTTP payload of traffic it directs to the Squid proxy service.

8. Click the Save & Next button and confirm by clicking the OK button in the pop-up that appears.
9. The Service Chain List screen will load. Wait a moment for the yellow "Deploy" ribbon to appear. When it does, click the Deploy button.

10. Click OK to acknowledge the successful deployment.
11. Visit a few more secure (HTTPS) websites (non-banking) using Chrome on the Windows Client. You should now see your username logged along with the HTTP requests you sent, similar to the example below:

12. Press <CTRL+C> to stop the tail tool.

Attention

This is the end of the lab module.
