You manage a Linux server for your organization. Robert Cronn, who was the project manager for the PRCC project, has resigned. His user ID was rcronn. The ClO of your organization has appointed Maggie Brown as the new project manager. Her user ID is mbrown. Your manager has asked you to lock Robert's account and move the project files for this project. Corey Flynn will be assuming Maggie Brown's old role.
