Red Hat Enterprise Linux 5 Cluster Suite Overview page 38

Chapter 1. Red Hat Cluster Suite Overview
Each luci instance has one user at initial installation — admin. Only the admin user may add systems
to a luci server. Also, the admin user can create additional user accounts and determine which users
are allowed to access clusters and computers registered in the luci database. It is possible to import
users as a batch operation in a new luci server, just as it is possible to import clusters and computers.
When a computer is added to a luci server to be administered, authentication is done once. No
authentication is necessary from then on (unless the certificate used is revoked by a CA). After that,
you can remotely configure and manage clusters and storage through the luci user interface. luci and
ricci communicate with each other via XML.
The following figures show sample displays of the three major luci tabs: homebase, cluster, and
storage.
For more information about Conga, refer to Configuring and Managing a Red Hat Cluster and the
online help available with the luci server.
