Your module should set PAM_USER using the pam_set_item() call before returning from pam_authenticate(). Some applications will attempt to prompt for the username before turning control over to PAM. In some cases this is unavoidable; in others, it's something that should probably be fixed in the application. gdm and kdm should both be able to get the username from PAM, although in practice I believe kdm doesn't currently do this.
