kdm authentication failures

Hello, I can't get kdm to authenticate my user. I built kdebase from revision 1236975, and I configured it as follows: mkdir build; cd build cmake .. \ -DCMAKE_INSTALL_PREFIX=/usr \ -DCMAKE_BUILD_TYPE=Release \ -DBUILD_ALL=On \ -DBUILD_DOC=Off \ -DWITH_SHADOW=On Yet I am unable to authenticate my user. This system doesn't have pam. This used to work with kde 3.5.10 when I ran configure with --with-shadow. Suggestions?
