In Element-based storage systems, authoritative cluster users can be created to enable login access to NetApp Hybrid Cloud Control depending on the permissions you want to grant "Administrator" or "Read-only" users. In addition to cluster users, there are also volume accounts, which enable clients to connect to volumes on a storage node. 

Manage the following types of accounts:

Enable LDAP

To use LDAP for any user account, you must first enable LDAP.

Steps

  1. Log in to NetApp Hybrid Cloud Control by providing the NetApp HCI or Element storage cluster administrator credentials.

  2. From the Dashboard, select on the top right Options icon and select User Management.

  3. From the Users page, select Configure LDAP.

  4. Define your LDAP configuration.

  5. Select the authentication type of Search and Bind or Direct Bind.

  6. Before you save the changes, select Test LDAP Log In at the top of the page, enter the user name and password of a user you know exists, and select Test.

  7. Select Save.

Manage authoritative cluster accounts

Authoritative user accounts are managed from the top right menu User Management option in NetApp Hybrid Cloud Control. These types of accounts enable you to authenticate against any storage asset associated with a NetApp Hybrid Cloud Control instance of nodes and clusters. With this account, you can manage volumes, accounts, access groups, and more across all clusters.

Create an authoritative cluster account

You can create an account by using NetApp Hybrid Cloud Control.

This account can be used to log in to the Hybrid Cloud Control, the per-node UI for the cluster, and the storage cluster in NetApp Element software.

Steps

  1. Log in to NetApp Hybrid Cloud Control by providing the NetApp HCI or Element storage cluster administrator credentials.

  2. From the Dashboard, select the top right Options icon, then select User Management.

  3. Select Create User.

  4. Select the authentication type of cluster or LDAP.

  5. Complete one of the following:

    • If you selected LDAP, enter the DN.

      Tip To use LDAP, you must first enable LDAP or LDAPS. See Enable LDAP.

    • If you selected Cluster as the Auth Type, enter a name and password for the new account.

  6. Select either Administrator or Read-only permissions.

    Tip To view the permissions from NetApp Element software, select Show legacy permissions. If you select a subset of these permissions, the account is assigned Read-only permissions. If you select all legacy permissions, the account is assigned Administrator permissions.
    Tip To ensure that all children of a group inherit permissions, create a DN organization admin group in the LDAP server. All the children accounts of that group will inherit those permissions.

  7. Check the box indicating that "I have read and accept the NetApp End User License Agreement."

  8. Select Create User.

Edit an authoritative cluster account

You can change the permissions or password on a user account by using NetApp Hybrid Cloud Control.

Steps

  1. Log in to NetApp Hybrid Cloud Control by providing the NetApp HCI or Element storage cluster administrator credentials.

  2. From the Dashboard, select on the icon in the top right and select User Management.

  3. Optionally filter the list of user accounts by selecting Cluster, LDAP, or Idp.

    If you configured users on the storage cluster with LDAP, those accounts show a User Type of "LDAP." If you configured users on the storage cluster with Idp, those accounts show a User Type of "Idp."

  4. In the Actions column in the table, expand the menu for the account and select Edit.

  5. Make changes as needed.

  6. Select Save.

  7. Log out of NetApp Hybrid Cloud Control.

  8. Update the credentials for the authoritative cluster asset using the NetApp Hybrid Cloud Control API.

    Note It might take the NetApp Hybrid Cloud Control UI up to 15 minutes to refresh the inventory. To manually refresh inventory, access the REST API UI inventory service https://<ManagementNodeIP>/inventory/1/ and run GET /installations​/{id} for the cluster.

  9. Log into NetApp Hybrid Cloud Control.

Delete an authoritative user account

You can delete one or more accounts when it is no longer needed. You can delete an LDAP user account.

Manage volume accounts

Volume accounts are managed within the NetApp Hybrid Cloud Control Volumes table. These accounts are specific only to the storage cluster on which they were created. These types of accounts enable you to set permissions on volumes across the network, but have no effect outside of those volumes.

A volume account contains the CHAP authentication required to access the volumes assigned to it.
