users - groups - profiles

[antonello facchetti]

On my edubuntu 7.04 I created via webmin through a csv file hundreds 
users, divided in 3 groups.

After thar  I realized that the users can't use cd-roms. floppy, audio.
They were created with the socalled "default" profile, nont with the 
"desktp" profile.

I found out that the file responsible for this is 
/etc/gnome-system/users/profiles.xml
So I tried to change it according to my needs.

The problem should be solved for the future: next time I'll use webmin 
to load new users they'll adhere to the modified default profile.

But now I'm looking for a way to put things in order in the existing 
system, i.e. grant cd floppy and audio access to all the users. 
Obviously I'm looking for an "elegant" solution, I don't want to change 
permissions to all users one by one.

BTW it would be nice if I could define which profile to use in webmin 
batch process, but I don't know how, yet.

Any ideas for all this?
