Connecting CMIS Workbench to Hana Cloud Platform

Hi -

I'm trying to connect to the Document Service via the Apache Chemistry's project "CMIS Workbench".  CMIS Workbench asks for the following:

URL,

binding type of AtomPub, Web Services, or Browser,

Username,

Password,

Authentication,

Compression,

Client Compression, and

Cookies

Then there's a Load Repositories button.  I've tried a variety of inputs on this screen, but none result in a successful connection.  I have gotten the Document Service working via some of the tutorials, and I can deploy and login to the Cockpit fine.

P.S. The release notes say the default protocol changed from AtomPub to JSON, but that's not an option with CMIS Workbench.  Is this related?

thanks

Max
