File in /etc/sudoers.d/ not recognized

Running a fresh install of Ubuntu server 16.04.1, I tried to add a file in /etc/sudoers.d/ to give one user root privileges for a certain command.

I added the file /etc/sudoers.d/servicetest with the following content:

servicetest ALL = (root) NOPASSWD: /bin/systemctl status *

The file /etc/sudoers is left untouched. It contains #includedir /etc/sudoers.d as the last line.
This setup is unfortunately not working, when executing an appropriate command with sudo as the user servicetest, I am still asked for the password. However, if I move the content of the file /etc/sudoers.d/servicetest to the end of /etc/sudoers, everything is working as expected.

What could be the cause of this issue? How can I get files in /etc/sudoers.d/ working?

The problem was not, as answered by IanC, caused by the file permissions (sudo happily accepts a file owned by root:root 0644, as I can confirm now, although it should of course be root:root 0440 for security reasons!), but by a newline at the end of the file which was preceded by a windows-style line ending ().

sudo only accepts as line endings.
