Definitions for "Trust Relationship"
Native American tribes are not foreign nations, but constitute "distinct political" communities "that may, more correctly, perhaps be denominated domestic, dependent nations" whose "relationship to the United States resembles that of a ward to his guardian." This language, in Cherokee Nation v. Georgia (1831), reaffirmed the doctrine of Federal trusteeship in Native American affairs. Today, a trust relationship or partnership refers more accurately to a relationship resembling that of a "beneficiary to a trustee."
Trust relationships are links between domains that enable pass-through authentication, in which a trusting domain honors the logon authentications of a trusted domain. With trust relationships, a user who has only one user account in one domain can potentially access the entire network. User accounts and global groups defined in a trusted domain can be given rights and resource permissions in a trusting domain, even though those accounts do not exist in the trusting domain's directory database.
