The admin client group is a system-defined client group with full access permissions for a given Broker. Each Broker has one admin client group, and you can enable ACLs for that client group, the same as with any other client group.

A client belonging to the admin client group has administrative access to a given Broker. Members of the admin client group can modify any Broker setting, and reconfigure the territories or local gateways to which the Broker belongs. As such, the admin client group is a control point for administrative access to a Broker. It is thus important that you use ACLs to secure the admin client group for each Broker as soon as possible.

For instructions on configuring ACLs for the admin client group, refer to About Configuring Client Group ACLs.
