identity management between multiple Active Dorectory forests


If i had 1000 separate Active Directory forests and without using forest trusts, how could i give access to all of them to a support team who had accounts in a 'support' forest.

I am thinking its a product like Front front identity management?

Thanks in advance

I think the product that you are thinking of the Active Directory Federated Services. This allows Forest to communicate over there boundry limits using claims based authentication / partnerships.

Microsoft FIM is more for Identity Management with in a Single Forest. I am sure you can also leverage Microsoft FIM with other products like ADFS however, out of the box Microsoft FIM will not work across multiple forests.
