Authentication of xs application on trial account

Hi,

I have a general question regarding authentication of xs application on trial account:

I created and deployed xs application on my trial account using the following guide:

https://help.hana.ondemand.com/help/frameset.htm?3762b229a4074fc59ac6a9ee7404f8c9.html

The result was a new application with the following server domain:

https://s3hanaxs.hanatrial.ondemand.com/.........

I would like to allow access to this server without any authentication, same way as it possible to deploy a simple java web application.

But according to the guide mentioned above, under the section of creating the .xsaccess file:

"Copy the following code into the .xsaccess file and save:

     { "exposed" : true, "default_file": "hello.xsjs" }

This configuration determines that the application is exposed via HTTP. Although no authentication is specified, all SAP HANA XS applications in SAP

HANA Cloud use SAML. To access the application, you will be authenticated with your SAP HANA Cloud credentials."

Is it possible to expose my xs application without authentication on my trial account, or is this option blocked ?

Thanks,

Dror
