I am currently setting up my home network to have centralised logins and

openldap and NFS to do this but I have a couple of questions both
closely related.

1. Is it possible to have an account caching facility similar to Windows
so that my laptops can login even if they are not connected to the
network.

2. Is it possible to have the home directories copied to and from the
client on login/logoff. Again I'm asking from the point of a laptop not
connected so it still has all the application configuration.

There's coda[0] a caching nfs-like filesystem that could be used though
last time I checked it could only handle a few hundreds of Megabytes.

You may get more mileage out of unison[1], which is a bidirectional file
synchroniser intended synchronise files between 2 mounted directories (or
ssh locations etc) when the files are edited on either/both sides.


As for LDAP you can set up /etc/nsswitch.conf on your laptop to check both
local passwd / shadow files _and_ the LDAP server for account authorisation,
group member shipt etc., thus when not connected to the LDAP server you can
log on provided you have a local account.

I'm sure there are tricks you can do with LDAP as well like having the
remote LDAP server and having a replicated server on the laptop and that way
you can always authenticate via the local LDAP server. Never done anything
like this though.
