Do Classic/OS9.x and OS X mix?

I’m trying to control an OS X machine from a Classic or OS9 machine and can’t get it to work.
Example script:
tell application “Finder” of machine “eppc://xxx.xxx.xxx.xxx”
beep
end tell

The target machine is running OS 10.3.x and the check box “Allow events from Mac OS 9” in the Sharing control panel is checked.

  1. If I run this script from Script Editor on another OS X machine, I’m asked a username and password . . . it works.

  2. If I run this script from Script Editor on an OS 9.x machine, or even from Classic on the same OS X machine in 1 above, with the same username and password . . . it responds:
    “Sorry, this user name was refused. Please try another name.”

No other name works.

Can anyone help?

On a fresh install, I had set both login and Remote Apple Events passwords the same. I had been using the same username as the admin of the OS X machine when sending username and password from the OS 9.x machine. It wasn’t working.

I now changed the password of Remote Apple Events to something else.

With some random series of letters as a username, and the new password, OS 9.X can control the OS X machines.

A glitch in password storage perhaps?

Go Figure.
