a plug-in called set user fingerpring.

Once you have finish and closed you will need to do the following.

While you may have heard that there are scripts to make kdm work this is not for the average user.

The Easy way in suse:

Go to the package manager and uninstall kdm then install gdm.

Then you should restart the system, when the login comes up it will be ugly. You will be asked to enter a login name then a password or fingerprint for authentication. Scan your finger if it works step one is complete.
