Configuring GUI Users
There are three classes of GUI users with different permissions for each.
1. Users with Administrator permission throughout a cluster can perform all possible actions
through the GUI.
2. Users with Operator permission on a server can view LifeKeeper configuration and status
informationand can bring resources into service and take them out of service on that server.
3. Users with Guest permission on a server can view LifeKeeper configuration and status
information on that server.
The GUI server must be invoked as root. During installation of the GUI package, an entry for the root
login and password is automatically configured in the GUI password file with
Administratorpermission, allowing root to perform all LifeKeeper tasks on that server via the GUI
application or web client. If you plan to allow users other than root to use LifeKeeper GUI clients, then
you need to configure LifeKeeper GUI users.
The best practice is to always grant permissions on a cluster-wide basis. It is possible to grant
permissions on a single-server basis, but that is confusing to users and makes it impossible to
perform administrative tasks.
User administration is performed through the command line interface, using lkpasswd, as described
below. Unless otherwise specified, all commands require you to enter the user's password twice.
