After installation the registry system owns three special groups. These groups have been created to contain some of the most common sets of users. They should always be considered when analyzing access policies for Businesses, Services, Bindings and tModels published to the registry.
These groups are named:
system#everyone - Contains everyone from everywhere including "guest" which is the default user account assigned to users who have yet to log into the system.
system#intranet - Contains everyone from the local intranet. In earlier releases of BEA AquaLogic Service Registry this was defined by an IP mask configured by the registry administrator. In current releases this group is a null set. It has no members.
system#registered - Contains everyone who has an account with this registry and who is logged in.
