I would like to create Lync 2010 Central Forest.

This is my situation:
I have root domain : root.domain and to subdomains : company.root.domain and group.root.domain in my main forest.
Lync 2010 is in domain: lync.company.root.domain. When I add new user (USER1) to group.root.domain - it has access to lync.
And now what I want to do:
- I have another domain:new.local in another forest.
-I disable the created user - USER1 in subdomain group.root.domain
- I create the same name user in domain: new.local
-I copy from USER1 (from resource forest -subdomain new.local ) the attribute objectSid into disabled USERS1 attribute msrtcsip-SidOriginator in main forest - domain group.root.domain.
Created accounts are clear: there is only First Name and Account Name. I don't have mailbox linked.
There is one way trust between domains: grupa.root.domain and new.local .
I would like to have access to Lync from domain: new.local.
What I made wrong?
P.S. I am going to copy all attributes manually. But maybe you can recommend good script.
Best Regards,
Paul
