There was an existing user called 'newuser' on the system. I wanted to remove the user and add it again so I ran the userdel command. When I went to add the user again I got the message displayed below.
# userdel newuser
UX: userdel: ERROR: newuser does not exist.
# useradd newuser
UX: useradd: ERROR: newuser is already in use. Choose another.
How can I delete this user?
