Hi:
Are you looking to integrate the user provisioning to Cloud for customer from AD ? If yes, we offer SOAP API's for employee replication, that can be used to provision / de-provision users in Cloud for customer from AD (this would be a custom implementation project though).
ADFS integration that you refer to above (I assume that is what you mean by Federation 2.0) is only used for front-end SAML based SSO.
Best regards
Venki
