$ getent passwd $USER

as I believe getent uses the /etc/nsswitch.conf settings while mkpasswd may not:
they often produce different lists or entries when I run them.

Not sure if it still applies, although it is still suggested in the docs:
install and run the cygserver service, then use passwd -R to stash your password
in the registry to allow network access.

Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada
