How to set an organization's accounts bought from MS CRM online services to work with an ADFS identity provider?

Hi!

My client has a couple of accounts paid for at MS CRM 2011 online services. Our application is able to integrate to MS CRM and now we have uplifted the authentication process to the claims-based level. We plan to deploy an ADFS instance and set their MS CRM accounts to communicate with our cloud app over tokens issued by our ADFS.

Is it possible to set the group of the organization's MS CRM accounts to use our ADFS? All the manuals I see on the internet are about settings on installing a stand-alone MS CRM application?

Thank you for the time!
