You can use gdmsetup to specify who is allowed to login through GDM. At least
you can with the version that comes with Debian lenny, but I think that's a
pretty old feature. You first need to tell it *not* to let everyone listed in
/etc/passwd, then add users to the whitelist.
Hope this helps,

Hi, I have a kubuntu 8.04 LTS machine acting as a file server (samba)
for our network with various users / permissions set up. Given that
from time to time I use the machine for the odd desktop-related task or
to do things I've not learnt to do via ssh, it has a (normally switched
off) monitor, keyboard and mouse attached. Users are listed in the
login window, despite turning off the Users "show list" option and only
having my own username selected under "selected users" in "Login
Manager" (this seems to be somewhat broken). Anyway, as I understand
it, this is just a convenience thing and a user could still manually
enter their username and password in the login window.
I am interested in preventing specific users from logging in locally to
a desktop but retaining their account for the purposes of serving up
files on the network. Can anyone point me in the right direction for
this? I'm not having any luck googling. This doesn't need to be
particularly clever, secure or a highly locked down configuration, just
a barrier to casual gui login attempts.
