MS Logon II documentation to implement in noVNC

Any feature you'd like to see in Ultr@VNC? Just propose it here.

MS Logon II documentation to implement in noVNC

Postby rgl » 2019-02-03 17:02

Hello,

When we use the noVNC 1.0.0 client connect to UltraVNC 1.2.2.3, noVNC complains with "Unsupported security types: 17,113".

Are those for the MS-Logon credentials types (as defined at http://www.uvnc.com/features/authentication.html)?

Is there any documentation about the Ms-Logon II type that can help implement this on noVNC?

FYI, I've also open an issue at https://github.com/novnc/noVNC/issues/1197.

I see!

17 is rfbUltraVNC
112 (0x70) is rfbUltraVNC_MsLogonIAuth
113 (0x71) is rfbUltraVNC_MsLogonIIAuth

Are these documented anywhere? Or are only "documented" in the source code "void ClientConnection::AuthMsLogonII()" at https://sourceforge.net/p/ultravnc/code ... .cpp#l3291? which BTW, is only the client implementation, where is the server implementation source code?

It would be nice to have all of this documented at https://github.com/rfbproto/rfbproto. What do you think?

Is your username on sourceforge cyberfox123?
