Indeed, it goes on to say:

"There is currently a bug (Bug #336214) in gdm which will prevent the umask
settings above from working if you are using gdm (the Debian default) as
your login manager. To work around this bug, edit /etc/gdm/Xsession and add
the line
	umask 002"

and now that I've tested that, the bug seems to remain in Ubuntu too.

The difficulty is to add the umask change in such a way that no matter what
type of session someone starts, the umask setting gets applied.  Looking at
the way ldm works (it promises to run /etc/profile) I would've guessed
umask in /etc/profile would work on your thin clients, though possibly not
if you logged directly in on the server or an installed edubuntu desktop
(which doesn't get started in the same way).

Adding it near the top of /etc/gdm/Xsession will probably set the umask for
local logins.  Thin client logins should hopefully be fixed by
/etc/profile, but if not, you might add a line near the top of

Let us know how you get on.  It might be nice to add something on this to
the edubuntu wiki.
