Of course, yes. And they are just two thing amongst many others.

Do you mean the webmin user management interface? Otherwise, could you send me

I'll try to: Let's presume a teacher wants to start some kind of project with
a couple of his students. We're working on a model where he can easily do the
He logs in into a web-based management interfaces. He uses some criteria (i.e.
the names of the students) to find the right people in the user database. He
creates a new "workgroup" and provides it with a name. (He doesn't need admin
privileges for that!)
When he does this, all these students will - at a special place, and as well
on Linux as on Windows clients - see a new folder which is named like the
workgroup and provides some kind of common workspace for the group.
Additionally, a mailing list for the workgroup will automatically be
Now he grants all students in his new workgroup the right, to use the internet
for the next three days without further explicit permission. Also he grants
this group the right to use the new, expensive color laser printer, but only
up to a limit of 50 pages.
To make this even more flexible, we probably will in fact _not_ distinguish
between students and teachers generally, but only provide the corresponding
users with different privileges - a teacher will in most cases be allowed to
create workgroup, a student won't. But maybe in some cases it's a good thing
to be able to allow a particular student to be able to allow others to - for
example - access the internet.
We're discussing a model with a bunch of different privileges, that can be
granted to users. These are, just to mention a few: create/manage workgroups,
allow internet, allow printing, use internet, use printer, and so on. These
privileges can also have time based or other limits, so simply using groups
would not be sufficient.
You see, this is going quite far when compared to what you are able to do with
skolelinux now, but it also imposes restrictions on what your installation
looks like. You have to use a certain way to do your user management and to
store your user accounts, have a special schema where your home directories
are located, have to use a special, modified printing system, use special IP
address management, PAM setup and so on. And this is the point where we have
problems with simply contributing to skolelinux, although we'd really
appreciate this: We cannot expect the skolelinux project to follow all these
restrictions and implications, but we also cannot provide our users with this
kind of integrated functionality without them.
