I have two separate organizations, two separate domains, and two forests. The two organizations have somewhat combined. I have created a two way trust between companyA.local and companyB.local. To make sharing of some resources easier I want to set up groups that traverse both domains. I can set up a group on either side but can only add users from that domain. What can I do to accomplish what I am trying to do? I am running at a 2008R2 functional level.
I am not sure if this is routed properly.
