When you use LDIFE to export Active Directory objects in a multiple domain forest, the export may fail. If the objects are exported, and imported into another domains Active Directory, the information may be incomplete.
When you use LDIFDE to export objects that are in the domain-naming contents, and you do NOT specify a server, LDIFDE searches for a global catalog server. If a global catalog server that is a member of a different domain is located, it may not have all the required Active Directory attributes for the objects that you want to export.
To workaround this behavior, use the -s <ServerName> parameter when you use LDIFDE in a multiple domain forest.
