I installed CF 10 on a server running Windows Server 2008 R2 Standard having logged into the server as a Windows user in the administrator group. I set up CF 10 Administrator to use a single password (the default). I can log into CF Admin when authenticating to the server with the same Windows credentials used when installing CF 10 but if I log into the server as another Windows user in the administrator group I cannot log into CF Admin; I get an Invalid Password error. I thought the whole point of the single password was so that anyone who can log into the server could log into CF Admin. It works like that for my CF 8 and CF 9 machines.
