Example One: Using Cascading Authentication

In the third part of the example we set %Service_Console to use cascading authentication. Then we access the Terminal.

Here are the steps:

Click %Service_Console on the Services page (click [Home] > [System Administration] > [Security] > [Services]) of the Management Portal.
On the Edit Definition page for %Service_Console click Unauthenticated and Password and make sure that no other mechanism is selected.
Click Save.
Now launch the Terminal. Click the InterSystems Launcher in your System Tray. Click Terminal from the menu.
Terminal prompts you for a user name and then a password. At each prompt, press Enter without supplying any information. InterSystems IRIS provides you with access to the Terminal anyway.
```
Username:
Password:
USER>
```
Execute the Write $UserName command at the prompt:
```
USER>Write $UserName
UnknownUser
USER>     
```
You are accessing the Terminal “unauthenticated” through the UnknownUser account. The authentication mechanism cascaded from Instance Authentication to Unauthenticated.
Close the Terminal. Click File—>Exit.
