By default, Cygwin will use the file content, and fallback to requesting
account info from Windows if an account is missing in pasdswd or group.

As an example, just try `id':

$ id
uid=3D1049577(corinna) gid=3D1049701(vinschen) groups=3D1049701(vinschen),5=
45(Users),14(REMOTE INTERACTIVE LOGON),4(INTERACTIVE),11(Authenticated User=
s),15(This Organization),4095(CurrentSession),66048(LOCAL),1049713(hirmke),=
1049089(Domain Users),1049148(Denied RODC Password Replication Group),40140=
8(Medium Mandatory Level)

Remoing the files is one way to test, but it's the more awkward one.
The better way is to create an /etc/nsswitch.conf file with the
following content, and then stop your Cygwin shell and restart it:

$ cat > /etc/nsswitch.conf <<EOF
passwd: db
group: db
EOF
$ exit

For the details, see the new documentation, please.

It's really, really worth to read it!

It also explains the above, see
