Any way to have a script display a dialog box over the login screen anymore?

[georgecm12]

Subject says it all... if I wanted to get input from the user via a dialog box while the computer is at the login window, is there any way to do so?

[Look]

Pretty sure JamfHelper will overlay the login Window.

/Library/Application Support/JAMF/bin/jamfHelper.app/Contents/MacOS/jamfHelper -help

[Look]

Oh sorry missed the part about user feedback, I think it does buttons but no text field, so depending on what your after it may or may not work.

Yeah, I was looking for a dialog box with a text input field.

That said, any tricks to getting jamfhelper to work at the login window? I tried a little bit and was unsuccessful. I think I was trying full screen... will the other presentation methods work? Is there something special I'd need to do to get jamfhelper to work at the login window?

[Look]

Hmmm might have been wrong, I can't get it to come up on the login screen either.
Certainly sending it as a command directly from Casper Remote doesn't work.
