[keycloak-user] ADFS Support Without Keycloak Server

Hi, I've read the announcement that Picketlink and Keycloak are merging. We currently use Picketlink to SSO with AD FS. Is that still possible with Keycloak or do I need a Keycloak server in between the application and ADFS? If I do need a server at the the moment are there any plans to change this during the merging of the two projects? Thank you, James.
