I have seen problems similar to those reported in "RE: Possible issue with
newest version of git (v 2.8) under Cygwin", but I did not want to hijack

For me, the problems have been elusive. Scripts that used to work would fail
as created directories had bad permissions, but I didn't have time to sort
them out. In the last week, I finally had time to read through the
documentation on the ntsec page and try some tests, and of course now I'm
having trouble reproducing the problems. You'd think that was a good thing,

I had been using /etc/passwd from mkpasswd, and based on recommendations
here, I modified nsswitch for passwd: db. This seemed to work fine, and I
decided I was all set.

Then Windows update rebooted over the weekend, and nothing worked, and
returning to 'files' resolved the problem.

The exacerbating factor here is that I have a laptop connected to my work
domain, but we use cached windows credentials when we are not on the work
LAN (like at home over the weekend). In this scenario, cygwin was apparently
unable to determine my username, and hence was unable to locate my home
directory. The username is apparently cached successfully if I reboot at
work and then go offline, but not if I reboot offline.

Does this mean I need to stay with 'passwd: files db' for the foreseeable
future, or is it possible to find the username in this scenario?
It's not the username per se, it's the fact that the db-only setting
doesn't allow o create valid passwd/group entries for your user.

So, yes.  In your scenario you should ideally revert back to "files db"
and create minimal /etc/passwd and /etc/group files.

/etc/passwd may contain only your own user account.  /etc/group
only the domain groups you're member of.  Everything "special" or
"local" will be picked up just fine by Cygwin then.  If there are
also files on your machine owned by some other domain user, it might
be helpful to add that account to /etc/passwd, too.

Great, thanks!
