question about dhcp configuration for group
 

Hi all,
I'm configuring a dhcp server (isc : dhcp-3.0pl2). I'd like to know how to configure some ippool/ip group following the user profile (based on his gid for example).
I saw it's possible to configure some groups, but I don't know what are these groups based on.
Following my clients (linux or windowz) the dhcpd.leases file gives me differents information :

lease 10.0.13.254 { #===>linux client
starts 2 2003/08/19 14:15:33;
ends 2 2003/08/19 14:25:33;
binding state active;
next binding state free;
hardware ethernet 00:09:5b:67:4b:fa;
}
lease 10.0.12.255 { #=====>win2K client
starts 2 2003/08/19 14:20:26;
ends 2 2003/08/19 14:30:26;
binding state active;
next binding state free;
hardware ethernet 00:0b:46:bd:5b:a3;
uid "\001\000\013F\275[\243";
client-hostname "rt03";
}

:confused: Are groups based on some of these information?

:confused: How to give client ip address following their group?

:confused: And finally, how to forbid users who configure manually their IP?

thx very well for u anwers.
