Oh no.  It has been 1 day and my "bug" is not fixed! I must blog about 
it so the world listens to me...

"I shouldn't have to disable an account in more than 1 way to disable it 
across the board."

Let see... one step procedures for disabling the user account

1) change password for that user
2) put an asterisk "*" at the beginning of the second field (before the 
encrypted password) in the file /etc/shadow.
3) set an account expiry date using chage
3) userdel is permanent one step procedure that works very well...

#2 is my preferred.
