This is probably a stupid question

[Madzsar, Andrew]

OK, I am sure this will show my naivety...
When setting up a thin client server I was trying to mess around and  
conserve resources by NOT intalling ubuntu-desktop.  I onl;y installed  
the ssh server and the thin client server pieces.  I found after  
running ltsp-build-client my thin clients would start up and get to a  
log in screen, but no username or password works.  I am assuming that  
this is because ltsp-build-client at some point gets the user info  
from ubuntu-desktop.  So I thought I could probably manually create an  
account (I've done it in OS X, it can't be too much different here?)  
but now I'm thinking that there is a reason you are supposed to  
install ubuntu-desktop.  Is there anyone that could shed some light on  
this.

Just looking for a little knowledge...
