The LDAP backend for ISC DHCP is used to store dhcp data, but wouldn't
be very useful for your purpose.

If you can run a script from the DHCP server when a machine registers,
then what you can do is to create a user/service allowed to modify DNS
entries (aadding a named ACI to the relative zone) and then simply use
the script to call 'nsupdate' and issue GSS-TSIG signed dns update
requests.

Simo.
