dhcp/dhcp-4.1.0-ldap-configuration.patch
David Cantrell 4bf24c8243 - Upgraded to ISC dhcp-4.1.0 
- Had to rename the -T option to -timeout as ISC is now using -T
- Allow package rebuilders to easily enable DHCPv6 support with: rpmbuild
    --with DHCPv6 dhcp.spec Note that Fedora is still using the 'dhcpv6'
    package, but some users may want to experiment with the ISC DHCPv6
    implementation locally.
