Your question is too general. You need to include more details such as what SSO software you are currently using and how does it interface with applications that do not have an API for it (like uVNC).

I wrote a wrapper around the VNCViewer.exe file which allows me to pass the username and password to it every time. It's basic, but works great.

Actually we use UltraVnc, we have lots of computers working with microsoft os.
Uvnc Server is installed on each computer.
We have a password which is configure on thoses UVnc servers.
Now, We want to use specific Active Directory accounts to use UltraVnc Viewer but we don't want to enter our login/password each time we want use the viewer.

That's why we are interested by the SSO system as proposed Real Vnc

This sounds very interesting, but I do not understand what you've done.

uVNC doesn't support SSO itself directly.

Since uVNC can take a Username and a Password as command line arguments, you can write a program that requests the Username/Password once and then always passes it to VNCViewer.exe so you don't have to do it manually each time.

Here's a quick and dirty HTA example of what I'm referring to:
If you're not familiar with HTA, it's an HTML application. Copy the contents of the code section into a text file and save it with a .hta extension. Then execute that file and the form should appear.

Code: Select all

Here's another version where it automatically fills in the Username field with the name of the User account logged onto the computer. I also made it automatically set focus to the VNC IP/Hostname textbox and make the VNC button default.

Thank you very much for the answers.

Your wrapper is really interesting but it doesn't exactly matches. My problem is about connection historical that UVnc proposed which is not present with your wrapper.
This is really usefull for us who need to launch many connections in the day.
