I've got several CentOS 4.x Linux boxes being installed in a corporate
network. I'd like to be able to set the hostnames via DHCP, but the
apparently Active Directory based network management is not
acknowledging the "DHCP_HOSTNAME" set names, although it seems to work
fine for Windows based DHCP clients.

Googling for an answer gets many thousands of hits, most of which are
pretty confused or confusing. Does anyone know how to do this
precisely, or have clear instructions? I remember some particular
setting in the dhclient.conf that involved the MAC address of the port
in question, but am having difficulty finding a reference.

I've found some additional notes that "dhcp-client-identifier" in
/etc/dhclient-eth0.conf and DHCP_HOSTNAME in
/etc/sysconfig/network-scripts/ifcfg-eth0 seem to be the keys, but I
succeeded in getting it working on one machine but not on the other
that I'm trying it with.

I'm using the MAC address of the port as the dhcp-client-identifier:
has anyone else gone through this lately?
