I am of the opinion that nscd causes far more problems than it solves
and wouldn't recommend usage.
For laptop purposes, you create the same user, same uid, same home
directory both as a local account and as an LDAP account so the laptop
will function either connected to LAN or not...it's tacky but it will
This is a good clean recommendation for NFS/Firewall...
