Ustvari dva navidezna računalnika - SimpleArbiter z diskom simpleArbiterDhcp
ter LDAPServer.
Na LDAPServer namesti strežnik LDAP. Strežnik naj skrbi za domeno
DC={DOMAIN},DC=kpov,DC=lusy,DC=fri,DC=uni-lj,DC=si
V imeniku ustvari uporabnika
CN={LDAP_USERNAME},ou=Users,DC={DOMAIN},DC=kpov,DC=lusy,DC=fri,DC=uni-lj,DC=si
z geslom {LDAP_PASSWORD} in uporabnika
CN={BIND_USERNAME},ou=Users,DC={DOMAIN},DC=kpov,DC=lusy,DC=fri,DC=uni-lj,DC=si
z geslom {BIND_PASSWORD}
Poskrbi, da se bo lahko klient s simpleArbiterDhcp povezal na LDAP strežnik na LDAPServer.
V primeru, da se klient poveže kot {BIND_USERNAME} z geslom {BIND_PASSWORD},
naj strežnik omogoči spreminjanje podatkov za objekt
CN={LDAP_USERNAME},ou=Users,DC={DOMAIN},DC=kpov,DC=lusy,DC=fri,DC=uni-lj,DC=si
ter ustvarjanje novih objektov v DC={DOMAIN},DC=kpov,DC=lusy,DC=fri,DC=uni-lj,DC=si

OU = Organizational Unit
DC = Domain Component
Na SimpleArbiter ustvari program, ki bo s pomočjo ldapsearch izpisal seznam lastnosti (otrok),
ki jih ima poljuben objekt v domeni {DOMAIN}.kpov.lusy.fri.uni-lj.si.
Ime objekta (CN) naj program sprejme kot prvi argument.

Create two virtual machines - SimpleArbiter using the disk simpleArbiterDhcp

Set up an LDAP server on LDAPServer. Make it responsible for

Create a user

Make sure that a client from simpleArbiterDhcp can connect to the LDAP server on
LDAPServer. If the client identifies themself as {BIND_USERNAME} with the password
{BIND_PASSWORD}, allow it to change data for the object
CN={LDAP_USERNAME},ou=Users,DC={DOMAIN},DC=kpov,DC=lusy,DC=fri,DC=uni-lj,DC=si

Create a program on SimpleArbiter which will use ldapsearch to output the list of properties

The program will be given the CN of the object as it's first argument.
