Reverse auto logon

I've just arrived in SuSE-land from Red Hatsville, where I was kicked off the train at milepost 9. The SuSE 9.0 install went OK (manual X config required on my IBM 600X, however). And, as usual, wireless did not work. That's OK, I'll work on that later when I have a month or so to waste. However, somehow the user account I created logs itself on automatically. I can't figure out how to get logon to stop and ask for the userid and password. I'm presently plowing through the books, but don't see it yet. Any clues? Thanks many times. George
