Using RDS in a domain trust DMZ

Howdy,

We have setup a one way transitive trust with a separate domain in our DMZ. Can I add multiple corporate partitions pointing to both domain forests in RDS 5.2.1 yet?

Example: We have our employees in example.com domain and customers in example.biz domain. We would like both sets of users to access DOORS via RDS so folks have just one password to remember.

Or would I need to try RDS in OS Authentication mode since the example.biz domain can forward authentication requests to example.com? (This assumes of course that our RDS server is sitting inside the example.biz DMZ.)

Thanks,

-Jeff
