NIS auth and ubuntu group

[Guillaume Desmottes]

Hi!

I'm deploying several rooms of computer with hoary.
The users of these PC are authenticated with a NIS server.  
This server send to the client the uid and gid of the user after his
auth.

I would like to add all logged user to some ubuntu group (cdrom, floppy,
plugdev, ...)
so they'll be able to mount floppy, cdrom, ...

Do you have any idea to make that the most elegant way as possible?
On the NIS server configuration?
On the clients configuration?
The file with the uid and gid can't be easily changed (this file come
daily from another
service of the university).

thanks a lot

	G.
