Thank you Mike! I am not getting credentials prompt when the connection is configured with no credentials, ignore server certificate and security mode is not set. In guacd the log says the following: guacd[45411]: INFO: No security mode specified. Defaulting to security mode negotiation with server. guacd[45411]: INFO: Resize method: none guacd[45411]: INFO: User "@ebfb17c7-3f46-42ff-bedd-7ae8ca589639" joined connection "$0e863f55-b2c9-41aa-8467-ddf390663b58" (1 users now present) guacd[45411]: INFO: Loading keymap "base" guacd[45411]: INFO: Loading keymap "en-us-qwerty" guacd[45411]: INFO: RDP server closed/refused connection: Server refused connection (wrong security type?) guacd[45411]: INFO: User "@ebfb17c7-3f46-42ff-bedd-7ae8ca589639" disconnected (0 users remain) guacd[45411]: INFO: Last user of connection "$0e863f55-b2c9-41aa-8467-ddf390663b58" disconnected
Is it perhaps related to NLA? The remote machine is a newer Windows with NLA required by default.

Does Guacamole have the option to ask the user for credentials via UI? Yes, if you don't set those parameters, the user will be prompted. You can also use credential pass-through using parameter tokens if your users' desktop credentials will match their Guacamole credentials (common with LDAP): https://guacamole.apache.org/doc/gug/configuring-guacamole.html#parameter-tokens<https://nam12.safelinks.protection.outlook.com/?url=https%3A%2F%2Fguacamole.apache.org%2Fdoc%2Fgug%2Fconfiguring-guacamole.html%23parameter-tokens&data=04%7C01%7CEli.Abramson%40honeywell.com%7Cd45b1398a1414d2e5ba508d9c2dea641%7C96ece5269c7d48b08daf8b93c90a5d18%7C0%7C0%7C637755083798200145%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=2ASZZbCSJ6uejrNeSmoLIKyA%2B%2B%2FU0gtUaCPhR4rGnSQ%3D&reserved=0> - Mike
