15.1 What is a Trust?

For authentication and name lookups to work across domains, a trust relationship must be created between the domains. The trust relationship includes a shared secret that can be used for both Kerberos and NTLM authentication and information that is used to support name resolution.

DSfW supports the following cross-forest trusts:
