Forest to perform the discovery in. Could be a short name or FQDN. User running the script must be able to authenticate in that forest and have access to Configuration Naming Context. (I.e. one-way trust from the specified forest to the local forest must be in place). Credentials specified in the Username parameter are not used for discovery. Only allowed with -Auto. If specified, Certificates used to establish the SSL connection will be verified. By default certification validation is disabled.
