Question about dhcp-client-identifier

[Darren]

Folks,

Does anyone know if it is possible to modify the string contained in the 
dhcp-client-identifier option so that it is actually the mac address 
when the server receives the packet?  Thereby forcing the DHCP server to 
key on mac address and ignore dhcp-client-identifier (UID).  Or, is 
there now an option (as of v.3.1.0) that can configure the server to key 
on MAC address and ignore dhcp-client-identifier ?  I couldn't find one 
in the config options nor could I find much discussion about this in the 
mail list archives.

Thank you!

Darren
