On a previous occasion I set up eBox using the defaults and it created a system user 'admin' in group 'eboxadmin' with the real name 'eBox Administrator'. As I understand it, it is this user that logs on automatically when the system starts.
This time when I installed eBox I managed to give this default user my own name, say 'john'. I configured everything in eBox but when I came to set up the users in eBox, I couldn't set up a user 'john'. I got an error message saying that the user already existed on the system. My eBox is useless if I can't have user 'john' receiving email and so on.
I have created a new user 'admin' on the host system with exactly the same permissions as 'john'. What I want to do now is to delete the 'john' account and make eBox use the 'admin' account instead. Is there a way to do this?
