Hmmmm, it's been a while since I've played that level. The stealth level is one of the most frustrating portions of the game, even if you know what to do to beat it. I'm always tempted to cheat and disable the AI for the level so I can just run right through it. But I digress...
I seem to remember that when I turned the lights out, I simply activated Force speed and ran as fast as I could to the door. If you're quick enough, you might be able to run past without the security officer noticing.
You can also find a walkthrough in Kurgan's Outcast Strategy website. The walkthrough for this particular level is located here
Hope that helps.
