If you have stale, orphan or other classifications of user accounts that need to be disabled and you do not have a policy in place to disable those accounts dynamically, you can do so manually.
Disable User Accounts
On the navbar, expand Identity Administration and select User Accounts.
Select the Disable User Account action.
Search for the user account that needs to be disabled and then check the box for the record returned.
Repeat step 3 for any other user accounts you need to disable.
When ready to commit your changes, click Submit.
Before submitting your changes, you can remove one or more user accounts from the cart by clicking the Selected icon and then clicking the Remove button beside the accounts you want to remove, as shown in the below image.
