INCLUDE subconfigs doesn't work

[MrMarvel]

Summary of the new feature / enhancement

Implementation of Include keyword

I would like to ask about this feature.
I have my subconfig like C:\ProgramData\ssh\sshd_config.d\my_config.conf to override base config like on linux. But it doesn't seem to work on windows.
sshd_config file:

# This is the sshd server system-wide configuration file.  See
# sshd_config(5) for more information.

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented.  Uncommented options override the
# default value.

Include __PROGRAMDATA__/ssh/ssh_config.d/*.conf

#Port 22
#AddressFamily any
#ListenAddress 0.0.0.0
#ListenAddress ::

C:\ProgramData\ssh\sshd_config.d\my_config.conf:

PasswordAuthentication no

I still can connect by password
There is no overrided info about it in docs https://github.com/PowerShell/Win32-OpenSSH/wiki/sshd_config
but base OpenBSD manual allows Include subconfigs.

Proposed technical implementation details (optional)

Does Include really substitute environment variables like PROGRAMDATA?

I don't think so.

The only Windows-specific change here seems a call to convertToForwardslash().

Does Include really substitute environment variables like PROGRAMDATA?

I tried full absolute path without globing like Include C:/ProgramData/ssh/ssh_config.d/my_config.conf.
It doesn't work either

[mgkuhn]

That string is passed on to a most curious function contrib/win32/win32compat/misc.c:is_absolute_path() to decide whether it is an absolute or relative path. (Why should that function concern itself with quotation marks?)

Try a relative path?

I have used

Match ALL
  Include /ProgramData/ssh/my_config.conf

In the bottom of my config file to allow for a standardized sshd_config and then do extensions/add-ons in a local file
