Overview

Cascading attributes enables managing settings in a flexible way.

• Instance administrator can define an instance-wide default setting, or lock the setting to prevent change by group owners.

• Group maintainers/owners can define a default setting for their group, or lock the setting to prevent change by sub-group maintainers/owners.

Behavior:

• When a group does not have a value (value is ‘nil`), cascade up the hierarchy to find the first non-nil value.

• Settings can be locked at any level to prevent groups/sub-groups from overriding.

• If the setting isn’t locked, the default can be overridden.

• An instance administrator or group maintainer/owner can push settings values to groups/sub-groups to override existing values, even when the setting is not otherwise locked.
