thank you very much, the patch applies nicely on ISC DHCP 4.2.1 source.
I did a quick look into the patch and I see it contains dhcp.schema updates
for dhcpRange6 attribute but it does not seem to be evaluated in ldap.c source.
Is there anybody on the list using it in production? If so can you post ldif
snippet for a DHCPv6 configuration?
