Single sign-on SSPI patch, other stuff...

Post by evg »

Recently, i did a little UltraVNC rewrite in order to use it in our corporate environment, adding the following features:
- single sign-on, authentication using SSPI (both the client and the server were patched) I had to change UltraVNC protocol a little to add this feature. In this patched version, if ms-logon is selected on the server, the default behavior is to try new SSPI auth, and if it fails, try ordinary ms-logon(user will get login/pass dialog prompt).
Patched client and server are incompatible with non-patched ones.
Also, I placed client-side SSPI code to the authSSP.dll, so it should be copied to the same directory where vncclient.exe is.
- NoDialog priviledge for ms logon(in addition to Full control, Interact and View) if it's set "Allowed" for the domain user and he tries to connect,
the user working at that moment will not get "Allow/Refuse Connection" dialog prompt. It is done so that only some domain users could connect without dialog prompt.

I think someone might find these features useful, so i uploaded .rar archive with that patched version(sources & binaries):
