Some Domains are missing from the Scopes of the Active Directory Discovery (4220607)

After clicking Add under the Scopes of an Active Directory Discovery, the root or some of the child domains or other forests or domains from other forests are not listed.

The nodes need to run under credentials from the other domains

When configuring the Active Directory Discovery, on the Name page under Credentials, select Use alternate credentials and select, or enter, credentials from the other domains or forests.

Note, if there are multiple domains or forests that you need to collect from you may have to create additional discoveries so that the nodes for those discoveries can run under credentials from the appropriate domains.
