In order to give those team members access to the Marketing Documents share, all the admin has to do is nest the Miami Marketing global group in the Marketing Documents domain local group, as illustrated below: The AGUDLP model is very similar to AGDLP but introduces the universal groups into the equation (hence the U in its name).
