I'm having a little trouble with the db_home: setting at work
(corporate network, not using /etc/passwd or /etc/group).  Regarding:

  https://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-mapping-nsswitch-home

I tried "db_home: /%H" and although my MINTTY session started in the
correct directory, ssh-keygen wanted to use the directory defined by
HOMESHARE instead, which points somewhere else (a local Unix server).
Note that both HOMEDRIVE (+HOMEPATH) and HOMESHARE ultimately point to
the same place:

DOS view of the world:

c:\>set | grep HOME
HOME=C:\Home
HOMEDRIVE=P:
HOMEPATH=\
HOMESHARE=\\corp.ad.broadcom.com\DENA\home\reisert

(mintty window with bash)

[LTDENA-REISERT:~] $ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key
(//corp.ad.broadcom.com/DENA/home/reisert/.ssh/id_rsa):

Cygwin view of the world:

[LTDENA-REISERT:~] $ set | grep -i home
CDPATH=.:/cygdrive/c/Home:/cygdrive/c/Home/dx4win:/cygdrive/c
HISTFILE=/cygdrive/c/Home/.bash_history
HOME=/cygdrive/c/Home
HOMEDRIVE=P:
HOMEPATH='\'
HOMESHARE='\\corp.ad.broadcom.com\DENA\home\reisert'
PWD=/cygdrive/c/Home

I can't explain what's going on.  I changed db_home to:

    db_home:   /cygdrive/C/Home

and it's working as expected.
