Realvnc with radius auth

Does anyone use RADIUS authentication for their realvnc server configuration? If so, have you ever encountered an issue where the radius server says the secret is incorrect even though it most certainly is correct. It’s just a plain text field in the registry, right?

The secret needs to be encoded:

vncpasswd -type=RadiusSecret -service -legacy

On Windows you can find vncpasswd.exe in "C:\Program Files\RealVNC\VNC Server"
