• The account contains the CHAP authentication required to access the volumes assigned to it.
• An account can have up to 2000 volumes assigned to it, but a volume can belong to only one account.
• User accounts can be managed from the NetApp Element Management extension point.
Using NetApp Hybrid Cloud Control, you can create and manage the following types of accounts:
• Administrator user accounts for the storage cluster
• Authoritative user accounts
• Volume accounts, specific only to the storage cluster on which they were created.
Storage cluster administrator accounts
There are two types of administrator accounts that can exist in a storage cluster running NetApp Element
software:
• Primary cluster administrator account: This administrator account is created when the cluster is created.
This account is the primary administrative account with the highest level of access to the cluster. This
account is analogous to a root user in a Linux system. You can change the password for this administrator
account.
• Cluster administrator account: You can give a cluster administrator account a limited range of
administrative access to perform specific tasks within a cluster. The credentials assigned to each cluster
administrator account are used to authenticate API and Element UI requests within the storage system.
A local (non-LDAP) cluster administrator account is required to access active nodes in a

cluster via the per-node UI. Account credentials are not required to access a node that is not
yet part of a cluster.
You can manage cluster administrator accounts by creating, deleting, and editing cluster administrator
accounts, changing the cluster administrator password, and configuring LDAP settings to manage system
access for users.
For details, see the SolidFire and Element Documentation
Authoritative user accounts
Authoritative user accounts can authenticate against any storage asset associated with the NetApp Hybrid
Cloud Control instance of nodes and clusters. With this account, you can manage volumes, accounts, access
groups, and more across all clusters.
Authoritative user accounts are managed from the top right menu User Management option in NetApp Hybrid
Cloud Control.
The authoritative storage cluster
users.
All users created on the authoritative storage cluster can log into the NetApp Hybrid Cloud Control. Users
created on other storage clusters cannot log into Hybrid Cloud Control.
• If your management node only has one storage cluster, then it is the authoritative cluster.
• If your management node has two or more storage clusters, one of those clusters is assigned as the
authoritative cluster and only users from that cluster can log into NetApp Hybrid Cloud Control.
