Manage cluster administrator user accounts

Contributors netapp-pcarriga

You can manage cluster administrator accounts for a SolidFire storage system by creating, deleting, and editing cluster administrator accounts, changing the cluster administrator password, and configuring LDAP settings to manage system access for users.

Storage cluster administrator account types

There are two types of administrator accounts that can exist in a storage cluster running NetApp Element software: the primary cluster administrator account and a cluster administrator account.

  • 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.

Note 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.

View cluster admin details

  1. To create a cluster-wide (non-LDAP) cluster administrator account, perform the following actions:

    1. Click Users > Cluster Admins.

  2. On the Cluster Admins page of the Users tab, you can view the following information.

    • ID: Sequential number assigned to the cluster administrator account.

    • Username: The name given to the cluster administrator account when it was created.

    • Access: The user permissions assigned to the user account. Possible values:

      • read

      • reporting

      • nodes

      • drives

      • volumes

      • accounts

      • clusterAdmins

      • administrator

      • supportAdmin

    Note All permissions are available to the administrator access type.

    • Type: The type of cluster administrator. Possible values:

      • Cluster

      • Ldap

    • Attributes: If the cluster administrator account was created using the Element API, this column shows any name-value pairs that were set using that method.

      See NetApp Element Software API Reference.

Create a cluster administrator account

You can create new cluster administrator accounts with permissions to allow or restrict access to specific areas of the storage system. When you set cluster administrator account permissions, the system grants read-only rights for any permissions you do not assign to the cluster administrator.

If you want to create an LDAP cluster administrator account, ensure that LDAP is configured on the cluster before you begin.

Enable LDAP authentication with the Element user interface

You can later change cluster administrator account privileges for reporting, nodes, drives, volumes, accounts, and cluster-level access. When you enable a permission, the system assigns write access for that level. The system grants the administrator user read-only access for the levels that you do not select.

You can also later remove any cluster administrator user account created by a system administrator. You cannot remove the primary cluster administrator account that was created when the cluster was created.

  1. To create a cluster-wide (non-LDAP) cluster administrator account, perform the following actions:

    1. Click Users > Cluster Admins.

    2. Click Create Cluster Admin.

    3. Select the Cluster user type.

    4. Enter a user name and password for the account and confirm password.

    5. Select user permissions to apply to the account.

    6. Select the check box to agree to the End User License Agreement.

    7. Click Create Cluster Admin.

  2. To create a cluster administrator account in the LDAP directory, perform the following actions:

    1. Click Cluster > LDAP.

    2. Ensure that LDAP Authentication is enabled.

    3. Click Test User Authentication and copy the distinguished name that appears for the user or one of the groups of which the user is a member so that you can paste it later.

    4. Click Users > Cluster Admins.

    5. Click Create Cluster Admin.

    6. Select the LDAP user type.

    7. In the Distinguished Name field, follow the example in the text box to enter a full distinguished name for the user or group. Alternatively, paste it from the distinguished name you copied earlier.

      If the distinguished name is part of a group, then any user that is a member of that group on the LDAP server will have permissions of this admin account.

      To add LDAP Cluster Admin users or groups the general format of the username is “LDAP:<Full Distinguished Name>”.

    8. Select user permissions to apply to the account.

    9. Select the check box to agree to the End User License Agreement.

    10. Click Create Cluster Admin.

Edit cluster administrator permissions

You can change cluster administrator account privileges for reporting, nodes, drives, volumes, accounts, and cluster-level access.

  1. Click Users > Cluster Admins.

  2. Click the Actions icon for the cluster administrator you want to edit.
