Windows 10/Server 2016 RDP work with Guacamole

Currently Guacamole 1.1.0 is not compatible with the default encryption of Windows. If you disable NLA it should work.

Open Registry editor ‘regedit’ and make the following settings:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp]
Change “SecurityLayer” value to dword:00000001
Verify “UserAuthentication” value is dword:0x00000000

This should work without reboot.

Or use NLA

If you want to use NLA you have to set SecurityMode to NLA of the connection. And you have to set username and password!

If your username and password in guacamole are the same on windows machine (if you have active directory and ldap auth in guacamole) you can use:

Username: ${GUAC_USERNAME}
Password: ${GUAC_PASSWORD}

Now guacamole uses the guacamole user credentials for the connection.
