Login screen appears on wrong user

We have a PC with several user accounts. We are all administrators and have Rhino 8 with the V-Ray plugin installed.

On one of our users, when V-Ray asks you to sign in to retrieve the license, you get the screen from the local server and click on the Login link and nothing happens. We were pulling our hair out why the browser is not opening. Then I logged in to my account and found a browser open with like 20 open tabs to log in. So the login screen opened in the browser on the other user account? Not even sure how that is technically possible, but okay.

Can you look into this bug?

Here is a video recording of it: https://share.icloud.com/photos/0cdk…aEVdIvoTonCDrw

I think what might have happened is that I installed V-Ray through my account and it was installed for the user and not the computer. Not sure if the installer even lets you choose. Either way, the log in screen should of course open in the SAME user account.

Thanks,

Armin.

Hi @seltzdesign ​,

Which V-Ray version do you have installed?

I suspect this has to do with our Unified Login service combined with the multi-user environment.
I’ll consult with my colleagues and get back to you.

Which V-Ray version do you have installed?

We are using V-Ray 7.00.03 in Rhino 8 on Windows 11.

I suspect this has to do with our Unified Login service combined with the multi-user environment.

That sounds about right. But I am still baffled how it is technically possible to open a browser tab in another administrators user account. How is that even allowed by Windows from a security standpoint??

@konstantin_chaos Did you ever look into this? It is still a problem on one of our shared machines. This time the login screen came up on a different user account. It is really ridicolous. We have never had similar issues with any other software and once again I am still curious how this is even technically possible for a process to open a link in a different user account! The main problem is that not all passwords for users are shared. So if for some reason Chaos asks you to log in again, which it does surprisingly often for no reason and the person whose account the browser window opened in is not around, it means you can’t use V-Ray, because there is no way to get to the login screen.

Can you please sort this out!

We have I think 5 or 6 user accounts on this PC, all of which are Administrators. Could it be that when you launch the login window you just look for the first Administrator account and open it in that?

Hello @seltzdesign ​!

One possible solution is to sign out from the Windows accounts instead of switching between them. Switching the users without logging out keeps the users in “Disconnected” status, where processes are still running. That is also the reason why the tabs are opened under disconnected users.

Please, let us know if that helps.

Kind regards,
