The problem here is that it's impossible to generate access
permissions for the pty with those weird accounts.  I like it
how Microsoft screws up otherwise working software with this
strange domain handling.

To fix this we have to be able to come up with a working user and group
account for these cases.  For that I need at least output from `whoami
/all'.  I wonder why supposedly nobody tried that after /fqdn didn't
work.

This may be fixable by somebody with such an account and willing to hack
on the Cygwin function pwdgrp::fetch_account_from_windows().  There's
already some code for the so-called "Windows accounts" which seem to
work in a similar fashion (albeit in this case the user has a local
account SID).

Alternatively I need at least a guinea pig with such an account,
