Version without ssh-lsa does not work with ssh keys on docker for Windows

[vcarluer]

Please answer the following

"OpenSSH for Windows" version
0.0.12.0

OS details
Microsoft Windows Server Core 2016 Docker container hosted by Microsoft Windows 2016.

What is failing
ssh key authentication

Expected output
Logon with public key

Actual output
Password prompt

Deployed with chocolatey.org package https://chocolatey.org/packages/openssh
Fallback to 0.0.10.0 works well

Got this with PowerShell 6 New-PSSession as well. Reverted to 0.0.11.0 and working again. In my case I installed from GH releases.

@vcarluer Please do you know a link to download the version with ssh-sla?

[vcarluer]

The version 0.0.10.0 available here have it (maybe the 0.0.11.0 too, didn't test)
https://github.com/PowerShell/Win32-OpenSSH/releases
I have installed it with chocolatey, so I didn't have test direct install from here but it should be the same.

v0.0.11.0 has ssh-lsa.dll as well.

On line 10 of the below linked dockerfile, add '-MaximumVersion 0.0.11.0' to keep your docker builds at 11 until this is fixed.

I'm looking into this.

Thanks @vcarluer

Found the issue. On the nanoserver docker image, SHGetKnownFolderPath(&FOLDERID_Profile) using the token generated by S4U for NTLM, is returning the system profile path

• C:\Windows\system32\config\systemprofile

I'll fix this in the next drop by avoiding this call and retrieving the user profile path from registry directly.

This is my dockerfile

FROM microsoft/nanoserver:latest

ADD OpenSSH-Win64 c:/openssh
RUN powershell -executionpolicy bypass -file c:\openssh\install-sshd.ps1
RUN powershell -c {cd c:\openssh; .\ssh-keygen -A;}
EXPOSE 22/tcp
RUN net user admin a /add
ENTRYPOINT net start sshd

#docker build . -t m1
