OSX Maverick AFP with Ubuntu settings

Maverick AFP with Ubuntu is having errors. Solution:
Edit /etc/netatalk/afpd.conf. At the end of the file are the default parameters:
-tcp -noddp -uamlist uams_dhx.so,uams_dhx2.so
Notice it is commented out. Uncomment the line and change it to:
-tcp -noddp -uamlist uams_dhx_passwd.so,uams_dhx2_passwd.so
