merging active directories, admt

[Erick Engelke]

I need to merge two active directories in different forests.

most users already exist in both domains. Eg I have a tom@a who
is the same person as tom@b, and they even have the same passwords.

I want to use admt or similar to merge everything the in the b
domain to trust the users in the a domain with the same userids.

Normally with admt you would migrate the users, creating a new sid, I want
to use the 'a' sids I already have.

Any suggestions?
