Assigning extended properties to Unix user accounts

Extended properties are meta objects, such as operating codes, cost codes, or cost accounting areas that cannot be mapped directly in One Identity Manager.

For detailed information about using extended properties, see the One Identity Manager Identity Management Base Module Administration Guide.

To specify extended properties for a user account

  1. In the Manager, select the Unix > User accounts category.

  2. Select the user account in the result list.

  3. Select Assign extended properties.

  4. In the Add assignments pane, assign extended properties.

    TIP: In the Remove assignments pane, you can remove assigned extended properties.

    To remove an assignment

    • Select the extended property and double-click .

  5. Save the changes.

Disabling AIX system user accounts

NOTE: The behavior described in the following, only applies to user accounts in an AIX system.

The way you disable user accounts depends on how they are managed.

Scenario:

The user account is linked to employees and is managed through account definitions.

User accounts managed through account definitions are disabled when the employee is temporarily or permanently disabled. The behavior depends on the user account manage level. Accounts with the Full managed manage level are disabled depending on the account definition settings. For user accounts with a manage level, configure the required behavior using the template in the UNXAccount.AIX_account_Locked column.

Scenario:

The user accounts are linked to employees. No account definition is applied.

User accounts managed through user account definitions are disabled when the employee is temporarily or permanently disabled. The behavior depends on the QER | Person | TemporaryDeactivation configuration parameter

  • If the configuration parameter is set, the employee’s user accounts are disabled when the employee is permanently or temporarily disabled.

  • If the configuration parameter is not set, the employee’s properties do not have any effect on the associated user accounts.

To disable the user account when the configuration parameter is disabled

  1. In the Manager, select the Unix > User accounts category.

  2. Select the user account in the result list.

  3. Select the Change main data task.

  4. On the Security tab, set the account_locked option.

  5. Save the changes.
Scenario:

User accounts not linked to employees.

To disable a user account that is no longer linked to an employee

  1. In the Manager, select the Unix > User accounts category.

  2. Select the user account in the result list.

  3. Select the Change main data task.

  4. On the Security tab, set the account_locked option.

  5. Save the changes.

For more detailed information about deactivating and deleting employees and user accounts, see the .One Identity Manager Target System Base Module Administration Guide
