Windows AD configuration for BI 4.1

Hi ,

I have a BI4.1 env and I am tried to configure windows AD. I have the BO server and the services accountin NA.Domain1.Com. I have the Windows AD users in nerf.domain2.com. There is no trust between these two environments. Can I still configure the windows AD? Can someone cite the steps? to do it. Is it mandatory to have my windows AD users and teh bo servers in one domains/ Can some one cite steps for my specific scenario? I can create some while on the BO server where i can provide the second domain login and password so that the windows ad can import users?

Thanks
