<pre>Postavi tri navidezne računalnike - SimpleArbiter z diska simpleArbiterDhcp,
RadiusA ter RadiusB. Na simpleArbiterDhcp preberi imeni domen DOMENA_A ter DOMENA_B,
uporabniški imeni USER_A in USER_B, gesli PASSWORD_A in PASSWORD_B ter skrivnosti
SECRET_A in SECRET_B. Poskrbi, da se bo lahko radius klient s SimpleArbiter povezal
na RadiusA s skrivnostjo SECRET_A ter na RadiusB s skrivnostjo SECRET_B. Poskrbi še,
da bo v nastavitvah OpenRadius na RadiusA obstajal uporabnik USER_A z geslom PASSWORD_A ter
na RadiusB uporabnik USER_B z geslom PASSWORD_B.

Poskrbi, da bo strežnik RadiusA odgovarjal na zahtevke za avtentikacijo uporabnikov na domeni DOMENA_A,
zahtevke za uporabnike na domeni DOMENA_B pa bo preposlal naprej na RadiusB. RadiusB naj odgovarja na
zahtevke za uporabnike na domeni DOMENA_B, zahtevke za uporabnike na DOMENA_A pa naj preprosto zavrže.</pre>
