Cross-Domain Authorization using CI Sessions

[eluser]Unknown[/eluser]
Hello folks,

First time posting here, and a rather out there question.

I am attempting to build a launchpad of sorts for my companies intranet. The idea would be to allow a user to log in to the launch pad, and the link to all of the pre-existing admin portals where they would already be logged in.

Not sure if this is possible, but I'm going to try. You can find a StackOverflow question that I posted, maybe a little more detailed.
