What is the default user name and password?

The default user name is sysadmin and the password is blank. After adding new
users, the sysadmin password should be changed to restrict to administrative use
only. The sysadmin user should never be deleted. To require a logon password,
set the 'Require Logon Password' flag on the System page of the Company Master.
Please refer to the 'Enable User Level Security' help topic for more details on
creating user names and passwords.
