deny duplicates

[Nicholas F Miller]

Has anyone had success implementing 'deny duplicates' or
'one-lease-per-client' to solve PXE boot systems taking two IPs? I have
read a bunch of posts on the subject but it seems that no-one has gotten
it to work. 

A machine exhibiting the behavior looks like this:

dhcp log:

lease 10.0.0.1 {
  starts 3 2007/01/10 23:20:03;
  ends 4 2007/01/11 00:20:03;
  tstp 4 2007/01/11 00:20:03;
  binding state active;
  next binding state free;
  hardware ethernet 00:13:72:1f:8f:dd;
}
lease 10.0.0.2 {
  starts 3 2007/01/10 23:20:46;
  ends 4 2007/01/11 00:20:46;
  tstp 4 2007/01/11 00:20:46;
  binding state active;
  next binding state free;
  hardware ethernet 00:13:72:1f:8f:dd;
  uid "\001\000\023r\037\217\335";
  client-hostname "ECCRNAC-PC51";
}

'deny duplicates' should solve this but it doesn't seems to be working.

We are running 3.0P2.
