Hi, How do you authenticate users from one forest in another forest? Eg what policies or groups should i use to achieve this? I have a oneway forest trust between worldpizza.com amd perupizza.com. I want users in : worldpizza.com to be able to authenticate in : perupizza.com are.perupizza.com lim.perupizza.com Thanks, C

I think you need to review what trusts are about. Hopefully this will help. You can only authenicate to one but thru the trust you can acces the other forests resources. http://technet.microsoft.com/en-us/... BTW its a common courtesy to update your last thread saying something like "hey I got the trust to work". In fact you could have saved some time and just update it with this issue since its a continuance of the original problem.
