AD integration for Role Mapping on APIGEE Edge SaaS SSO

We are evaluating APIGEE SaaS for our use case and one of the things that we are not able to find a solution for is the Active Directory integration while doing SSO.

The question to the community or to the APIGEE Team is if AD Group mapping to APIGEE roles in SaaS is possible. If not, what are some of the solution that other APIGEE consumers has attempted, to achieve the same result.

Thanks
