#.SYNOPSIS
#   Get distinguished name of an AD object.
#.DESCRIPTION
#   Extract the fully qualified distinguished name (DN) for an object
#   in Active Directory after searching for it by name and schema class.
#   The $Class parameter will often be user, group, OU, or computer.
#   If the $Domain parameter is left blank, it defaults to local domain.
#   Only searches the Domain container, not Configuration or Schema.
