About The Default Cluster Domain - Dell DX6000 Administration Manual

Users who are not in any realm defined by the domain manager can perform only actions that
require no authentication.
• Application developer: Responsible for creating content in the domain (that is, buckets and
objects for which they have privileges).

4.2. About the Default Cluster Domain

The default cluster domain is an optional domain whose name exactly matches the cluster name.
Every unnamed object and every named object that has no domain explicitly defined for it belong
to the default cluster domain. Creating a default cluster domain enables your cluster to use the
following features:
• POST authentication for unnamed objects.
• Disambiguation of cluster names in a roll-up cluster.
The domain name is stored as part of the object's system metadata. Provided every domain
name you manage is unique, there will never be a collision between named objects from different
clusters if those clusters are combined (such as in a disaster recovery cluster).
• Convenience when working with objects. Application developers do not have to explicitly set a
domain name as the Host in the request to perform operations on an object (such as create,
update, or delete).
Note
Every unnamed object belongs to the default cluster domain and, if you use security,
POST permissions are supported for unnamed objects on the default cluster domain
only. There is no reason to create a default cluster domain if your client applications use
unnamed objects only without POST authentication.
The following figure shows an example Cluster Settings page with one tenant
configured (cluster.example.com). If this domain name matches the cluster name,
cluster.example.com is the default cluster domain for this cluster.
