Ustvari dva navidezna računalnika - SimpleArbiter z diskom simpleArbiterDhcp ter LDAPServer.
Na LDAPServer namesti strežnik LDAP. 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
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.
