I believe the commented out values are indeed the defaults, but
nevertheless I have the same issue with this set explicitly and sshd
restarted.
As an aside, I also ran:
echo vagrant | passwd --stdin root
to ensure a valid root password was possible, even when not set previously.

If any know knows why it's not working, I'd appreciate it, otherwise
I'll try again tomorrow with a clear head once I can get
/var/log/secure back and working again ;)

Cheers,
James
