Although settings are configured at a given level, they are always configured for
a specific mode. It is not necessary to configure settings for all modes within a
level. The cluster mode is a special case. Because there can only be one cluster,
all settings configured for the cluster mode can be said to be configured at the
cluster level.

all settings configured for the cluster mode can be said to be configured at the
cluster level.
You should normally configure most settings at the cluster level. However,
settings that have been specifically configured at lower levels will override
settings configured at higher levels. Thus, you can override cluster-mode settings
with group-mode or machine-mode settings.

with group-mode or machine-mode settings.
For example, you might start by configuring the Good Neighbor Table in cluster
mode; all machines in the cluster would use that configuration. Then, you might
also configure this table in machine mode for machine
mode; all machines in the cluster would use that configuration. Then, you might
also configure this table in machine mode for machine
newyork
. In this case, all
other machines in the cluster will still use the good neighbor table defined at the
cluster level, but the machine
cluster level, but the machine
newyork
will override the cluster settings with its
individual machine mode settings.
The ability to override cluster settings for specific groups or machines gives you
a lot of flexibility. However, if you find yourself configuring many settings
individually in machine mode, you will lose much of the ease of administration
that clusters were intended to provide.

Initial Configuration Settings
For most features, when you begin to configure settings for a new mode, those
settings will initially be empty by default. There is a distinction between empty
settings and having no settings in a mode. As an example, consider a very simple
cluster composed of one group and one machine. Imagine that you have an LDAP
query configured at the cluster level. There are no settings configured at the group
or machine levels:
