Can I override loginwindow on Tiger?

Question

My software authorizes the user prior to booting Mac OS X (Tiger and Leopard.) I want to use SFAuthorizationPluginView to create a plugin to attempt to use our pre-boot authorization (cached securely) for user login to Mac OS X for single-sign-on capability. I have not yet validated if that will even work for Leopard, but am assuming I will be able to do it. (Dangerous, I know.)

The question is how can I do this for Tiger and will that solution work for Leopard?

I continue to research, if I find a solution I will share.

Answer 1

What I'd expect to do is to change the /etc/authorization database to accept your authorization as sufficient, but the comments around system.login.console don't lead me to expect that would work. You could circumvent LoginWindow by providing your own login-like app which you bring up with launchd instead of com.apple.loginwindow, but that seems like using a sledgehammer to crack a nut.

Answer 2

While looking around after posting my question on several lists (here is the link to my SO post), I came across your question. I have the same problem, only that I am trying to do this on Snow Leopard (and maybe Leopard). Did you make any progress ? I managed to write a plugin which is being loaded, but I do not know how to forward the credentials and skip the login window screen. Did you find any useful resources ?
