Delete Users

This article explains how to delete system administration users.

System administration users are not the same as database users.

This procedure is carried out using ConfD.

Prerequisites

To perform this task you must be a member of the exaadm group.

Procedure

The following examples use ConfD through the command-line tool confd_client, which is available on all database nodes. You can also access ConfD through XML-RPC in your own Python programs. For more information, see ConfD.

Placeholder values are indicated with UPPERCASE characters. Replace the placeholders with your own values.

  1. Connect to EXAClusterOS (COS) on the cluster using c4 connect -t <DEPLOYMENT>[.<NODE>]/cos. For example:

    ./c4 connect -t 1.11/cos

    If you do not specify a node, c4 will connect to the first active node in the deployment. If the cluster is configured with an access node, the first node is the access node (usually n10).

    For more information about how to use c4 connect, see How to use c4.

  2. To find the exact user name, use the ConfD job user_list. In this example, the user name is ADMIN2:

    confd_client user_list
    ...
    ADMIN2:
      additional_groups: []
      authorized_keys: []
      group: exaadm
      id: 1005

  3. To delete the user, use the ConfD job user_delete. For example: 

    confd_client user_delete username: ADMIN2

Verification

To verify that the user has been deleted, use the ConfD job user_list: 

confd_client user_list

The user should no longer be listed.
