login error or not

Hi all,
I am a newbie on this forum…i just move out from M$ vista …I already installed opensuse 11.2 gnome. I still have a problem with my login accounts. I have user nr1 and user nr2, both with same wrights. when I log out from user nr1, I got the login screen-thats good. But, when I reboot/restart my machine, it seems to go back to user nr1 without login screen- without asking about password!!! I need to have that login screen on, for both users, with passwords. I guess I did something wrong there, but I dont know what I`ve done.
Some help will be appreciated!

You have automatic login feature turned on.

Run gdmsetup and you can disable it from there.
