Its broken. Someone posted a patch that works. I will repost it in a couple
of days with my 'OBSERVATIONS: ...' posting that will detail my SLS 1.01/2
installation, configuration and testing experiences.

NIS does not work at the moment on Linux but I'm sure that will be rectified.

It stops people with black hats :( copying your password file and trying to
crack the encryted passwords with a password cracker. The passwords are held
in /etc/shadow with permissions set to 600 (ie. no normal user can snarf it.
You don't want to disable this feature and if you did you would have to
recompile a large portion of the system software which now uses shadow
passwords.
