+Para verificar que o OCSP funciona correctamente, o cliente conectou ao servidor OpenVPN:
+primeiro, sem o servidor OCSP a correr, uma segunda vez com ele a correr e com o certificado correcto
+e uma terceira vez com um certificado revogado. Fizemos estes testes sabendo que o 
+cliente e o servidor já estavam correctamente configurados.
+
+Verificamos que, como é suposto: sem OCSP não é possivel autenticar; com OCSP e com certificado válido,
+podemos autenticar; e com OCSP mas com certificado revogado, a autenticação falha.
