Guacamole como ignorar certificados RDP

Tenho um servidor Ubuntu que executa o guacamole 1.5.5. Ao conectar a um host Windows 11, ele falha porque o nome ao qual estou me conectando (10.0.0.5) não corresponde ao nome do certificado (Test-Client).

Ao adicionar um cliente Ubuntu com xrdp não tive problemas, tudo funciona bem.

Adicionei um host Windows 11 com esta configuração:

<?xml version="1.0" encoding="UTF-8"?>
<user-mapping>
<authorize
    username="admin"
    password="password"
    encoding="plain">
    <connection name="Windows-Test-Client">
        <protocol>rdp</protocol>
        <param name="hostname">10.0.0.5</param>
        <param name="port">3389</param>
        <param name="username">azureuser</param>
        <param name="password">password</param>
        <param name="ignore-cert">true></param>
        <param name="security">any</param>
    </connection>
</authorize>

o que me confunde, porque configurei ignore-cert como true.

Além disso, testei a porta RDP assim:

telnet 10.0.0.5 3389

Trying 10.0.0.5...
Connected to 10.0.0.5.
Escape character is '^]'.

o que me diz que a porta funciona.

Meu guacamol.properties se parece com isso:

guacd-hostname: localhost
guacd-port: 4822
lib-directory: /usr/local/lib
auth-provider: net.sourceforge.guacamole.net.auth.simple.SimpleAuthenticationProvider
rdp-ignore-cert: true

Qualquer ajuda é muito apreciada.
