Chapter 9. Managing user accounts using the command line

This chapter includes basic description of user life cycle in IdM (Identity Management). The following sections show you how to:

  • Create user accounts
  • Activate stage user accounts
  • Preserve user accounts
  • Delete active, stage, or preserved user accounts
  • Restore preserved user accounts

9.1. User life cycle

IdM (Identity Management) supports three user account states:

  • Stage users are not allowed to authenticate. This is an initial state. Some of the user account properties required for active users cannot be set, for example, group membership.
  • Active users are allowed to authenticate. All required user account properties must be set in this state.
  • Preserved users are former active users that are considered inactive and cannot authenticate to IdM. Preserved users retain most of the account properties they had as active users, but they are not part of any user groups.

You can delete user entries permanently from the IdM database.

Important

Deleted user accounts cannot be restored. When you delete a user account, all the information associated with the account is permanently lost.

A new administrator can only be created by a user with administrator rights, such as the default admin user. If you accidentally delete all administrator accounts, the Directory Manager must create a new administrator manually in the Directory Server.

Warning

Do not delete the admin user. As admin is a pre-defined user required by IdM, this operation causes problems with certain commands. If you want to define and use an alternative admin user, disable the pre-defined admin user with ipa user-disable admin after you granted admin permissions to at least one different user.

9.2. Adding users using the command line

You can add user as:

  • Active — user accounts which can be actively used by their users.
  • Stage — users cannot use these accounts. Use it if you want to prepare new user accounts. When users are ready to use their accounts, then you can activate them.

The following procedure describes adding active users to the IdM server with the ipa user-add command.

Similarly, you can create stage user accounts with the ipa stageuser-add command.

Note

IdM automatically assigns a unique user ID (UID) to the new user accounts. You can also do this manually, however, the server does not validate whether the UID number is unique. Due to this, multiple user entries might have the same ID number assigned. Red Hat recommends to prevent having multiple entries with the same UID.

Prerequisites

Procedure

  1. Open terminal and connect to the IdM server.
  2. Add user login, user’s first name, last name and optionally, you can also add their email address.

    $ ipa user-add user_login --first=first_name --last=last_name --email=email_address

    IdM supports user names that can be described by the following regular expression:

    [a-zA-Z0-9_.][a-zA-Z0-9_.-]{0,252}[a-zA-Z0-9_.$-]?
    Note

    User names ending with the trailing dollar sign ($) are supported to enable Samba 3.x machine support.

    If you add a user name containing uppercase characters, IdM automatically converts the name to lowercase when saving it. Therefore, IdM always requires to enter user names in lowercase when logging in. Additionally, it is not possible to add user names which differ only in letter casing, such as user and User.

    The default maximum length for user names is 32 characters. To change it, use the ipa config-mod --maxusername command. For example, to increase the maximum user name length to 64 characters:

    $ ipa config-mod --maxusername=64
     Maximum username length: 64
     ...

    The ipa user-add command includes a lot of parameters. To list them all, use the ipa help command:

    $ ipa help user-add

    For details about ipa help command, see What is the IPA help.

You can verify if the new user account is successfully created by listing all IdM user accounts:

$ ipa $ ipa user-find

This command lists all user accounts with details.

9.3. Activating users using the command line

To activate a user account by moving it from stage to active, use the ipa stageuser-activate command.

Prerequisites

Procedure

  1. Open terminal and connect to the IdM server.
  2. Activate the user account with the following command:

    $ ipa stageuser-activate user_login
    -------------------------
    Stage user user_login activated
    -------------------------
    ...

You can verify if the new user account is successfully created by listing all IdM user accounts:

$ ipa $ ipa user-find

This command lists all user accounts with details.

9.4. Preserving users using the command line

To preserve a user account, use the ipa user-del or ipa stageuser-del commands.

Prerequisites

Procedure

  1. Open terminal and connect to the IdM server.
  2. Preserve the user account with the following command:

    $ ipa user-del --preserve user_login
    --------------------
    Deleted user "user_login"
    --------------------

9.5. Deleting users using the command line

IdM (Identity Management) enables you to delete users permanently. You can delete:

  • Active users with the following command: ipa user-del
  • Stage users with the following command: ipa stageuser-del
  • Preserved users with the following command: ipa user-del

When deleting multiple users, use the --continue option to force the command to continue regardless of errors. A summary of the successful and failed operations is printed to the stdout standard output stream when the command completes.

$ ipa user-del --continue user1 user2 user3

If you do not use --continue, the command proceeds with deleting users until it encounters an error, after which it stops and exits.

Prerequisites

Procedure

  1. Open terminal and connect to the IdM server.
  2. Delete the user account with the following command:

    $ ipa user-del user_login
    --------------------
    Deleted user "user_login"
    --------------------

The user account has been permanently deleted from IdM.

9.6. Restoring users using the command line

You can restore a preserved users to:

  • Active users: ipa user-undel
  • Stage users: ipa user-stage

Restoring a user account does not restore all of the account’s previous attributes. For example, the user’s password is not restored and must be set again.

Prerequisites

Procedure

  1. Open terminal and connect to the IdM server.
  2. Activate the user account with the following command:

    $ ipa user-undel user_login
    ------------------------------
    Undeleted user account "user_login"
    ------------------------------

    Alternatively, you can restore user accounts as staged:

    $ ipa user-stage user_login
    ------------------------------
    Staged user account "user_login"
    ------------------------------

You can verify if the new user account is successfully created by listing all IdM user accounts:

$ ipa $ ipa user-find

This command lists all user accounts with details.
