Example Setup (cont.)

Now, open your favorite REST client. This example uses the Postman browser plug-in.

Create a GET request and specify the Basic as the authentication type and SuperUser/SYS as the Username/Password.
The URL looks like this
```
http://localhost:52773/csp/user/authenticationEx
```
Note that the port number displayed here, 52773, is the default InterSystems IRIS web server port. The port for your instance may be different.
Click Send. The application returns the username and the user's roles. When InterSystems IRIS is installed with minimal as the initial security setting, SuperUser has the %ALL role.

Note:

SuperUser is a predefined user account that InterSystems IRIS installs by default. To learn more about predefined users, see Predefined User Accounts.

There are a number of free REST clients available as stand alone applications and browser plug-ins.
