Most commonly, this issue means that there was most likely some cruft left behind when the the account was removed the first time. Is the user "rackleaf" mentioned in the file
or does the user "rackleaf" have any files that belong to them in the directory
I would suggest reviewing the file
and the directory
and remove any entries relating to that user. It may also be best to copy any important data if you believe it may be important in the future. I hope this helps!
