Changing User Authentication After Installation

I have installed opensuse 10.3 and used the simple method of creating users. Now I have joined a windows domain by following the GUI in yast, but I am having trouble changing the user authentication to use windows domain. How can I do this?

When I load up user configuration in yast I do not see any option to switch to this form of authentication.

Best Regards,

this took me a while to notice, but after restarting the machine it automatically changes the user authentication to window domain

guess it was a pretty silly mistake
