In Domains from the Active Directory, it is possible to have a trust relationship between different domains. However, even though it is possible to synchronize users from a “principal” domain, it is not possible to synchronize users from a different domain using the same Group Synchronization, even if there is a trust relationship between the domains.
Domain users must be returned using the query configured in the Active Directory Group Synchronization. If it’s desired that senhasegura have access and synchronize users from another domain, it’s necessary to create a new group synchronization. This, however, must be connected to the server that effectively manages these users.
Therefore, to ensure effective synchronization of users across different domains, it is crucial that there are different group synchronizations, each pointing to their respective domain.
