Error: `System.InvalidOperationException: No process is associated with this object` when using gsudo with Admin by Request

Issue Description

I'm trying to use gsudo on my workstation. We use something called Admin by Request that sort of replace the Windows UAV. When launching a command in a user console, I always end up with the error System.InvalidOperationException: No process is associated with this object.. Is there something that can be done about that?

Steps to Reproduce

  1. Launch PowerShell in a Windows Terminal (I've also tested cmd, MinGW32 and outside a Windows Terminal)
  2. Enter gsudo --debug ls
  3. Get the Admin by Request "UAV" and validate it
  4. See the console be filled until line "Elevating process"
  5. See the gsudo service console pop up
  6. See the gsudo service console close down
  7. See the backtrace on the main console

Context:

  • Windows version: Windows 10 22H2
  • gsudo version: gsudo v2.4.2 (Branch.tags-v2.4.2.Sha.c23b1024b4974f5d90cf82968637bdb4c8924ca7) (installed with winget)

Hi @Bouska,

This is a bug on AdminByRequest, not gsudo. They are intercepting Start-Process -verb RunAs but not returning the elevated process handle.
Btw, arent gsudo and AdminByRequest incompatible per definition? AdminByRequest belongs to regulated environments and wants to intercept and log all elevations, while gsudo cache is an alternate way to grant them. Let me know if a SysAdmin officially wants to make them work together.
Anyway AdminByRequest technical support never answered my messages. I don't own a license so they are ghosting me. You may have better luck than I.

IDk if this issue is exactly the same or similar to #141, but the bottom line is, ABR api interception is not clean.

Hi @gerardog

Thanks for checking this issue. I suspected the issue came from AdminRequest, guess I'll do without using gsudo. I'm closing the issue.
