Citrix Broker SDK - Configuration Slots and Machine Configurations
SHORT DESCRIPTION
Overview of assigning a collection of related settings to a desktop group.
LONG DESCRIPTION
Collections of related settings may be applied to individual desktop groups
through the creation of configuration slots and machine configurations.
A configuration slot defines a collection of related settings that are to be
associated with that slot. Each machine configuration is associated with a
single configuration slot and provides specific values for settings of that
slot.
The SettingsGroup property of the configuration slot determines the
particular collection of related settings that are associated with that
slot. These groups are defined by Citrix and are not modifiable by
administrators. For example, there is a particular group of Profile
management specific settings that may be associated with a configuration
slot. Because of the close association between a configuration slot and its
collection of related settings, the full set of configuration slots is
created during the site creation.
Each machine configuration is associated with a single configuration slot.
The machine configuration contains policy data that provides specific values
for the settings associated with that configuration slot.
Every value set in a machine configuration's policy must belong to the
configuration slot's settings group. Therefore the appropriate SDK snap-in
must be used to create the policy data. For example, the Profile management
snap-in must be used to create the policy data for a machine configuration
associated with the Profile management configuration slot.
To have particular policy settings applied to the machines in a desktop
group, a machine configuration is associated with that desktop group. A
machine configuration may be associated with multiple desktop groups. A
desktop group may be associated with multiple machine configurations.
When a machine configuration is associated with a desktop group, the
configuration inherits the delegated administration restrictions of the
desktop group. Thus, if a machine configuration is associated with multiple
desktop groups, an administrator can only modify the policy data of the
configuration if the administrator has permission to modify every one of
those desktop groups.
