By default, new external and forest trusts in Windows Server 2003 Active Directory Domain Services enforce SID filtering. SID filtering is used to prevent attacks from malicious users who might try to grant elevated user rights to another user account. Enforcing SID filtering on forest trusts does not prevent migrations to domains within the same forest from using SID history and will not affect your universal group access control strategy.
