The first kdm theme was created by Petter Reinholdtsen based on the
kdm theme in kubuntu and is licensed under the GNU General Public License. 

Based on the existent kdm and gdm themes, in combination with the
oxygen-air theme (GPL 2008 Xavier Araque) and a new background image
from the Debian moreblue-orbit theme, a refurbished theme was created
by Andreas B. Mundt (GPL 2010). 

The xml-files defining the gdm and kdm theme are mostly identical now,
except for the user entries: gdm uses a combined "user-pw-entry", where
kdm has a "user-entry" and a "pw-entry".
