Feel free to contribute one.  My major concern was to get a complete
description in the documentation.  It's hard (for me) to condense this
to a shorter versions without knowing at all what people need and not
need.  Ultimatly there won't be a condensed version which matches
everybody's needs anyway.

Try this instead:

  passwd: db
  group: db
  db_shell: /bin/tcsh

This should work for you without any passwd and group files, provided
you're the only user of your machine anyway.

As outlined in https://cygwin.com/ml/cygwin/2015-03/msg00380.html
this is certainly not a desired result, so I'd like to see how
this occurs and how we can avoid this in the next Cygwin version.

So, *before* you make the above suggested change, can you please provide
the following information:

- In a CMD shell, cd to C:\cygwin{64}\bin, call the following two
  commands, and paste the output into your reply:

    getent passwd %USERNAME%
    id

- Please provide your /etc/passwd file content, or at least the
  passwd entry of your account.

The https://cygwin.com/cygwin-ug-net/ntsec.html document explains
how not to mess with AD, if that's not desired.  See the above
suggestion.


Thanks and HTH,
