useradd command to create accounts for KDE Yast users

Hello, Thanks for reading my request. I am new with SUSE, so thank-you for your consideration. Here it is: I would like to add user accounts to a SUSE 9.2 server system using a shell command, similar to useradd, that is able to create a login account that works for users logging in through the KDE Yast interface(XDMCP query from a PC say) as well as, of-course, the standard ssh, rlogin way. If a useraddYast shell command does not exist, what, in your opinion, is the best method to create an account that works ?, With Much Thanks for your kind help, David A.-
