Permission required:
Administrator privileges
Non-administrators with permission to delete users from within their own group. Refer to Granting or Removing User Group Permissions for details.
Where: Navigator > Resources > Users
Right-click the user and select Delete User.
Caution: A dialog confirms if you want to delete or disable the user’s login (deactive the user but keep the user definition in the database). Deleting a user means deleting all resources that user created: the user’s rules, lists, cases, and so on. Click More Information for a list of these resources. If you need these resources, copy them to another resource group before deleting the user. If you need more time, disable the login first to prevent unauthorized access.
In the dialog box, click Delete to delete the user and the listed user's resources or click Disable Login to disable the user.
