Apple Remote Desktop Administrator Access Using Directory
You can also grant Apple Remote Desktop administrator access without enabling any
local users at all by enabling group-based authorization if the client computers are
bound to a directory service. When you use specially named groups from your
Directory Services master domain, you don’t have to add users and passwords to the
client computers for Apple Remote Desktop access and privileges.
When Directory Services authorization is enabled on a client, the user name and
password you supply when you authenticate to the computer are checked in the
directory. If the name belongs to one of the Apple Remote Desktop access groups, you
are granted the access privileges assigned to the group.
