This all started here:
https://cygwin.com/ml/cygwin/2019-02/msg00109.html

followed up with

https://cygwin.com/ml/cygwin/2019-02/msg00113.html

tl;dr: The easy and fast way out didn't work for accounts from
other domains than the machine's primary domain due to caching.

So I thought it's a good idea to fetch the correct groupnames by an
additional LDAP call, but the performance hit is apparently too high in
some environments.

This is all more or less moot as soon as OpenSSH 8.0 comes out, which
will contain patches to handle user and group names case-insensitive,
finally.
