Za povezavo na strežnik LDAP uporabi Jxplorer, kjer tudi ustvariš novega uporabnika z danim imenom in geslom. Na LDAPServer namesti strežnik LDAP in sicer slapd z apt-get install slapd. Na SimpleArbiter preberi ime domene DOMENA, uporabniško ime USER_A, geslo PASS_A, uporabniško ime BIND_DN ter geslo BIND_PASS. Poskrbi, da se bo lahko klient s simpleArbiterDhcp povezal na LDAP strežnik na LDAPServer. V primeru, da se klient poveže kot BIND_DN z geslom BIND_PASS, naj strežnik omogoči spreminjanje podatkov za objekt CN=USER_A,DC=DOMENA,DC=kpov,DC=lusy,DC=fri,DC=uni-lj,DC=si ter ustvarjanje novih objektov v DC=DOMENA,DC=kpov,DC=lusy,DC=fri,DC=uni-lj,DC=si CN = Common Name OU = Organizational Unit DC = Domain Component Na SimpleArbiter ustvari program, ki bo s pomočjo ldapsearch izpisala seznam lastnosti (otrok), ki jih ima poljuben objekt v domeni DOMENA.kpov.lusy.fri.uni-lj.si. Ime objekta (CN) naj program sprejme kot prvi argument.
