Here is my user id (from the id command) when I log in from the office:

Here is the same when I've logged in with the machine at home:
uid=1293438(MAN+User(244862)) gid=1293438
(MAN) is the domain.
That likely means that when you connect from home, you cannot talk to
the
corporate domain server or you are ion a different domain. The domain
part is only shown when it isn't the primary domain IIRC and since the
numerical user instead of the name is shown, that SID did not resolve.
The actual problem I'm having is that Cygwin tools like ssh, git,
etc. can't find my .ssh
directory. They are looking in "/" rather than my home directory.
Depending on how this is set up in your domain, you might need to point
either Cygwin or sshd to use a separate local directory. You have no
network access on Windows (i.e. you won't be able to access any fils
shares) until you've authenticated with a password.
I tried copying my .ssh directory from my home to "/" and although
it was created, the
files have the wrong permissions and I'm unable to change them.
You would need to be either an admin and/or the user who installed
Cygwin for that to work, but you shouldn't do that.
Is there something I can tweak to get Cygwin to understand which
user I am so the ssh
stuff can start working again?
If Cygwin doesn't know who you are, then that means Windows doesn't know
either, so fixing this on the Cygwin side won't get you much further.

I think Windows knows who I am. I log into the machine using my normal
domain login
credentials. The machine looks the way it does when I log in when the
machine is in the
office - the desktop is the same, etc. - it's not acting like I'm a
new user or anything
like that.
Everything on the Windows side seems to be working fine. The only
issue I've found is with
Cygwin. Is there a way (short of removing and reinstalling Cygwin)
that I can get Cygwin
to recognize my current user so ssh and git can know where my home
directory is located?
I also have had to deal with this problem. You should certainly read
https://cygwin.com/cygwin-ug-net/ntsec.html.
After much experimenting and consultation with Corinna, we decided the
best solution for me was:
* Create /etc/passwd and /etc/group files
o For /etc/passwd, I included just my account, and I actually
editted it further to use my preferred username (rather than my
domain username) and my correct home directory
* Edit /etc/nsswitch.conf with:
o passwd: files
o group: files
This is not the generally recommended configuration, but in the
situation where you cannot reach the domain server, it may be the best
alternative. You may or may not need to back these changes out when you
are back at work. I have not had a problem at work, but we are only
loosely connected to the domain, so YMMV.
