`command not found` when connecting to OpenSSH server using Git Bash as DefaultShell and disabling pseudo-terminal allocation

[andriyDev]

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest version
• Search the existing issues.

Steps to reproduce

1. On machine running OpenSSH server, install Git Bash and set DefaultShell for OpenSSH Server to the path of Git Bash (on my machine, I used D:\Programs\Git\usr\bin\bash.exe).
2. On another machine, connect to the OpenSSH server with ssh -T <host_address>.

I am attempting to use VS Code Remote-SSH to connect from my laptop to my desktop (running OpenSSH). This fails to connect. The underlying command being used is ssh -T <host_address>. I have configured OpenSSH to use DefaultShell to be Git Bash. Note: clearing this makes it work though now when I need to ssh into my desktop I need to manually run bash.

Expected behavior

> ssh -T <address>
echo hi<C-d>
hi

Actual behavior

> ssh -T <address>

I'm able to repro this. Are you able to configure VS Code Remote-SSH to connect without disabling pty?

[andriyDev]

I think Remote-SSH unconditionally disables the pty specifically for setting up the VS code server stuff. I've tried playing with the settings. There is one saying "permitPtyAllocation" but it didn't seem to have any effect.
