Linux dhcpd.conf not authoritative

DHCP on linux defaults a server to "not authoritative" this means the server is not authoritative for the local subnet. The server must be changed to authoritative before options can be recieved by clients, this is resolved by the uncommenting or adding the following line to the global section of dhcpd.conf.

# If this DHCP server is the official DHCP server for the local
# network, the authoritative directive should be uncommented.
authoritative;
