Thin clients (as far as I understand) mean that a
server does all the work, and the clients serve only
as terminals. This is not what I want to do, since all
the computers are pretty strong and all of them are to
perform independent intensive calculations, since most
of the users work most of their time on one particular
station. Thin client would be huge waste of the
existing facilities.

As I said, some of the users have their "primary"
workstations - computers they work on most of the
time. Almost all of them are doing intensive number
crunching and have huge I/O to/from the hard drive.
Putting their home directories on one central location
will decrease their performance due to longer (much
longer) read/write times. That's why we keep several
home directories.

This is designed for thin clients (correct me if I'm
wrong). Not good for us

We don't have a single computer with windows on it.

I was also suggested to use LDAP to maintain users and
maintain the rest of the system idually per computer,
using a common configuration engine
