Multiple login accounts with root privileges

["ganesh mahadevan" <ganesh.was.mahadevan () gmail com>]

Hi,

I was testing a thin client box and found that I could login as Root,
Administrator and Admin (all with the same password).  whoami
indicated 'root' in all three cases.  Is this some sort of aliasing
going on? I may not be entirely correct on this but shouldn't the
number of users with root privileges be restricted?  What is your
advice on this issue?

Thanks in advance.
