Integrasi server DHCP dengan OpenLDAP

Tutorial kali ini kita akan membahas integrasi server DHCP dengan OpenLDAP untuk menyimpan konfigurasi pemberian alamat IP secara otomatis, pada linux ubuntu 12.04 precise pangolin. Integrasi server DHCP dengan OpenLDAP sangat berguna apabila kita memiliki beberapa subnet jaringan yang dikelola oleh beberapa server DHCP. OpenLDAP mampu menyimpan konfigurasi DHCP dengan banyak subnet yang berbeda. Aplikasi yang digunakan adalah ISC DHCP Server default dari ubuntu 12.04. Dengan asumsi kita sudah memiliki server OpenLDAP sebagai Single Sign On.
